Setting up a connection through a proxy server. Proper use of a proxy server

Traveling through the Internet using your computer, laptop, or even mobile device, every user sooner or later faces the problem of accessing some resources. Of course, the question immediately arises: what is the reason for this and how to get rid of such troubles. Or, for example, in a company office there are many computers and one access to the global network. How, in this case, can all workplaces be connected to the Internet while still being able to control the traffic usage of each employee? And security issues office network from external influence (hackers) in this case immediately find themselves in the foreground. Using a certain type of connection in such situations seems to be the most reasonable solution, so let’s take a closer look at all aspects of setting up a proxy server on Windows 7.

Let’s say right away that for faster and anonymous work on the Internet, it is better not to save money by using all kinds of free proxies. They are very slow, because there are already a lot of people sitting on them. Therefore, we decided to take several private proxies to set up a proxy server on Windows 7 as part of this article.

What is it and what functions does it perform?

Everyone has some idea of ​​mediation. This concept is usually associated with trade. A proxy server is also a kind of intermediary. But this has nothing to do with trading. Through a proxy server, which is a complex of network computer programs, client (software or hardware system component) requests data from various network services.

For example, an Internet browser through which the user views resources global network(sites), first connects to a proxy server that makes external requests. The web server on which the desired site is located sends an information packet in response. The proxy server generates this packet in accordance with its settings and sends it to the client (Internet browser). As a result, the user sees the website he needs on the screen. In this case, the visit to the resource is associated with a completely different address than the IP address of the computer from which the request was made.

In an office network, the proxy server is connected through a router, which in this case represents an access point. A single computer is connected directly through its network card.

Connecting and setting up a proxy server on Windows 7

Let's say a user wants to anonymously visit a site or cannot get to it because the IP addresses of the network to which his computer is part of are blocked. It is necessary to create the connection correctly, that is, configure the proxy server. Depending on the Internet browser used, this process can be multidirectional, but only before opening the proxy server settings through any browser. If earlier for different browsers it was possible to use non-matching IP addresses, but now this will not work, except perhaps Mozilla Firefox. Connecting and setting up a proxy server affects the settings of all Internet browsers used in Windows 7.

How to configure the Internet Explorer system browser

Specialized resources where you can view the necessary data for free can be easily found through an Internet search. It is enough to enter a request, for example, like “Proxy list”. Some resources that post such data:

• foxtools.ru/Proxy
• proxy-fresh.ru/proxy/
• spys.ru and others.

Setting up Opera on your computer

IN latest versions Browser proxy server settings are tied to system ones. It follows from this that the process of setting up a proxy server is the same whether through a browser or using a panel Windows management 7. The same options window will open local network, as is the case with Internet Explorer. To verify this, in Opera, select “Menu//Settings//Browser//Change proxy server settings”.

Setting up Mozilla Firefox

How to set up Safari

Select the settings tab from the drop-down list of the main browser menu, then in the window that opens, go to the “Add-ons” menu item, where click the button to change proxy settings.

How to disable proxy

To disable the proxy server in browsers, just go to the settings network parameters uncheck the box that allows its use. In Mozilla Firefox, you can apply individual settings.

Installing browser add-ons

To connect to Internet resources through a proxy server, browser plugins are often used to bypass site blocking by redirecting traffic. These are add-ons such as ZenMate, friGate, Web Proxy and many others. For each browser on the Internet you can find more than one option.

Let's take the friGate application for Mozilla Firefox as an example. After installation in the panel opposite address bar The plugin icon appears, by clicking on which you can select the necessary settings, turning on, for example, a proxy server for all sites or selecting resources from the list.

How to connect via VPN

When using virtual private network(VPN) all traffic personal computer passed through a proxy server. This guarantees high level anonymity, and the connection speed does not drop. To use a VPN connection in Windows 7, you can install CyberGhost 5, free version which is sufficient to ensure anonymous surfing user on the Internet.

When you enable protection, the program will advise you to upgrade and switch to paid version. If you wish to receive additional functionality you can take advantage of the offer. Otherwise, the request should be ignored.

When installing CyberGhost 5, program settings are configured automatically. This creates virtual adapter TAP-Windows Adapter V9 and the new network connection running through it. In the properties of the Internet protocol component (TCP/IPv4) used network card VPN connection DNS servers are automatically registered.

Why proxy doesn't work and how to fix it

Sites may not open if the proxy is unavailable. This means that the server has stopped working. This often happens when using free servers, which can be created temporarily. Failures are also possible during peak server loads. In this case, you should use other addresses from free or paid lists proxy servers. What else? If the proxy server is configured incorrectly, the Internet will also not respond, so you should pay special attention to these questions. Follow the setup method suggested in the article, and the problem “Cannot connect to the proxy server” will be avoided in most cases.

A proxy server (from English proxy - authorized representative) is a kind of intermediary server on the network. The user first connects to the proxy server, and the proxy then connects to another server that hosts the right resource(e-mail, search engine, etc.). The user does not connect directly to the requested resource, but does it through an “intermediary,” which has a number of advantages. Learn more about setting up a proxy server in Windows system 7 read our article.

Why do you need a proxy server?

1. The proxy checks whether the requested data is in temporary memory. And if they are, then it does not re-download information from the Internet, which saves traffic.
2. Network access can be shared among several users.
3. The proxy server maintains the anonymity of requests, since the information is not transmitted further to the Internet and does not remain on the user’s computer; The IP address from which the request was made also cannot say anything about the user’s computer, only about the proxy server, and it may be located in another country.
4. A proxy protects your computer from external influences by transmitting only the requested data and filtering out unnecessary data.
5. Due to the fact that all data on the computer comes only from the proxy server, you can bypass the blocking of some sites, especially those that are installed independently by your telecom operator.

MTS has blocked many torrents for its users, but the proxy server “deceives” the built-in blocking system, since for it the proxy server is just some Internet resource, one of those that can be opened. But the data on the proxy itself comes from completely different sites, sometimes blocked: it is quite difficult to track this programmatically. This is what programs such as Anonymizer and Tor stand for.

How to install: step-by-step instructions

Let's look at how to install a proxy server on Windows 7.

Before you start setting up a proxy server, you need to know its IP address and port. The list of proxy servers can be viewed on the following sites:

• 2ip.ru/proxy;
• hideme.ru/proxy-list;
• spys.ru;
• xseo.in/freeproxy.

Having decided on the choice of proxy server and finding out the address and port, proceed to setup:

Video: how to set up a proxy server on Windows 7

What should you do if your computer can't connect to the proxy server?

The proxy server may not respond because it is simply unavailable. In this case, wait or try using the services of some other proxy server.

It is possible that an incorrect address or port was entered when setting up the proxy server.

Check this through the control panel: open the “Internet Options” section, in the window that opens, the “Connections” tab. And click “Settings” (in the subsection “Configuring local network parameters”, if your connection is via local network cable or Wi-Fi, or “Set up dial-up and virtual private networks” if you have a modem). In the window, find the option “Use a proxy server for this connection” and check the entered address and port.

Viruses may interfere with the connection to the proxy server. In this case, it is worth conducting a deep scan of your computer with an antivirus program.

Setting up a proxy server in browsers

If for some reason you need to set proxy server parameters separately for different browsers, then setting through the control panel will not work for you. You will need to manually configure the proxy server for each browser. Let's look at how this is done in the most popular of them.

Mozilla Firefox

Opera

Google Chrome, Yandex, Amigo and more

Other browsers

In all other browsers the actions are similar. First you need to delete your browsing history, cache and cookies, then open the network settings and configure connection settings through proxy servers. There is nothing complicated about this: you just need to dig a little into the settings.

How to find out the IP address

If a proxy server is used on your computer, then open “Control Panel” -> “Network and Sharing Center” shared access" Click on active connection and select "Properties" from the list. The TCP/IP field contains the address of the gateway through which the connection is made. This is the IP address of your proxy server.

If your computer is at home or corporate network, and the proxy server is configured on another computer on the network, then this will help you system command tracert. From “Start”, enable “Command Prompt” and type “tracert [external host name]” and press Enter. Instead of [external host name], write the name of any computer on the network. A list of nodes appears, sorted by hierarchy. This way you can find the proxy server address and port.

There is another option: use online services that can analyze your connection and determine your IP. And since you are connecting through a proxy server, the IP address of your proxy will be indicated. The following sites will help you:

• http://www.leader.ru/secure/who.html;
• http://www.whatismyip.com;
• http://tulahelp.ru/ip.

How to disable the proxy server

If you have a proxy server installed in general for a local or modem network, then follow these steps:

1. Open Control Panel.
2. Find the "Internet Options" (or "Internet Options") section and open it.
3. The settings window will open. Switch to the "Connections" tab. Further actions differ for modem (bluetooth, USB, or so on) and local connections (including Wi-Fi). Do the same as when connecting a proxy server, only in reverse: uncheck the boxes.
   1. If you connect to the Internet via a USB or Bluetooth modem, then do the following: in the “Setting up a dial-up…” subsection, find and click on the name of your modem that you use to access the Internet, then click on the “Settings” button. In the window that opens, uncheck the “Use proxy...” item.
   2. If your computer receives the Internet via a local connection - Wi-Fi, wired - then follow these steps: in the “Setting up... local network” subsection, enable the settings. A window will open, uncheck the “Use proxy...” item.
4. Ready.

If the proxy server is installed in the settings of a separate browser, then open that browser and go to the network settings (as was done above) and uncheck the “Use a proxy server...” item. Do this for each browser in which you have created a connection through a proxy server.

A proxy server is a useful thing for those who want to hide their IP address, once again protect themselves from viruses, and save traffic. However, there are also disadvantages: problems on the side of the proxy server itself. For example, if it is overloaded, it will significantly reduce throughput: and it will take longer to load data onto your computer than is possible with your Internet speed. In addition, the proxy server itself may contain viruses, so look for a reliable proxy server and do not trust dubious sources.

A proxy is an intermediate server that acts as an intermediary between the user’s computer and resources on the network. Using a proxy, you can change your IP address, and also, in some cases, protect your PC from network attacks. In this article we will talk about how to install and configure a proxy on your computer.

The procedure for enabling a proxy cannot be fully called an installation, since its use does not require additional software. However, there are browser extensions that manage address lists, as well as desktop software with similar functions.

In order to get started, you need to obtain data to access the server. This is done on specialized resources that provide such services.

The structure of the received data differs from service provider to service provider, but the composition remains the same. This is the IP address, connection port, username and password. The last two positions may be missing if authorization on the server is not required.

183.120.238.130:8080@lumpics:hf74ju4

In the first part (before the “dog”) we see the server address, and after the colon – the port. In the second, also separated by a colon, is the username and password.

183.120.238.130:8080

This structure is used to load lists into various programs, which are capable of using large number proxy in your work. In personal accounts of services, this information is usually presented in a more convenient form.

Option 1: Special programs

Such software is divided into two groups. The first only allows you to switch between addresses, and the second allows you to enable proxies for individual applications and the system as a whole. For example, let’s look at two programs – Proxy Switcher and Proxifier.

Proxy Switcher

This program allows you to switch between addresses provided by developers, uploaded as a list, or created manually. Has a built-in checker to check the viability of servers.

• After launching the program, we will see a list of addresses to which we can already connect to change the IP. This is done simply: select the server, right-click and click on the item context menu "Switch to this Server".

  

• If you need to add your data, click the red button with a plus on top panel tools.

  

Here we enter the IP and port, as well as the username and password. If there is no authorization data, then leave the last two fields empty. Click OK.



• The connection is made in exactly the same way as with the built-in sheet. The same menu also contains the function "Test this Server". It is needed for preliminary testing of functionality.

  

• If you have a sheet of paper in your hands ( text file) with addresses, ports and authorization data (see above), then it can be loaded into the program in the menu "File – Import from text file".

  

Proxifier

This software makes it possible not only to use a proxy for the entire system, but also to launch applications, for example, game clients, with a change of address.

To enter your data into the program, perform the following steps:

In order to make it work only specific program through a proxy, you must perform the following procedure:

1. We refuse to install a proxy by default (see point 4 above).
2. In the next dialog box, open the rules settings block with the button "Yes".

   

3. Next, click "Add".

   

4. Give the new rule a name, and then click “ Browse".

   

5. Find it on disk executable file programs or games and click "Open".

   

6. In the dropdown list "Action" select our previously created proxy.

   

7. Click OK.

   

Now the selected application will work through the selected server. The main advantage of this approach is that it can be used to enable address change even for programs that do not support this function.

Option 2: System Settings

Settings system parameters network allows you to route all traffic, both incoming and outgoing, through a proxy server. If connections have been created, you can set your own addresses for each of them.

1. Launching the menu "Run" (Win+R) and write a command to access "Control Panels".

   

2. Let's go to the applet "Browser Options"(in Win XP "Internet Options").

   

3. Let's go to the tab "Connections". Here we see two buttons with the name "Tune". The first opens the settings window for the selected connection.

   

   The second does the same, but for all connections.

   

4. To enable a proxy on one connection, click on the corresponding button and in the window that opens, check the checkbox "Use a proxy server...".

   

   

   Here we register the address and port received from the service. The field selection depends on the proxy type. Most often, it is enough to check the box that allows you to use the same address for all protocols. Click OK.

   

   Check the box next to the item that prohibits the use of proxies for local addresses. This is done so that internal traffic on the local network does not go through this server.

   

   Click OK and then "Apply".

   

5. If you need to allow all traffic through a proxy, then go to the network settings by clicking on the button indicated above (step 3). Here we check the boxes in the block shown in the screenshot, specify the IP and connection port, and then apply these parameters.

   

   Option 4: Setting up a proxy in programs

   Many programs that actively use the Internet in their work have their own settings for redirecting traffic through a proxy server. Let's take applications as an example. This function is enabled in the settings, on the corresponding tab. All required fields for address and port, as well as username and password are provided here.

   

   Conclusion

   Using proxy servers to connect to the Internet gives us the opportunity to visit blocked sites, as well as change our address for other purposes. Here we can give one piece of advice: try not to use free worksheets, since the speed of such servers, due to the high load, leaves much to be desired. In addition, it is unknown for what purposes other people could “use” it.

   Decide for yourself whether to install special programs to manage connections or make do system settings, application (browser) settings or extensions. All options give the same result, only the time spent entering data and additional functionality changes.

It is impossible to imagine today's mobile technologies without their connection to the Internet. Each of us has ever received or transmitted information via the World Wide Web, but not everyone has thought about how this happens and what the transmission depends on. So, we come across a proxy server every day when working on the Internet, communicating with friends and simply viewing mail. It remains to understand the purpose, functionality and principle of its operation.

Proxy Knowledge Base

As soon as the user connects his device (not necessarily a PC) to the World Wide Web, installs a browser program and goes to his first website, his first meeting with the proxy server occurs. Each device on the Internet has its own IP address, which encrypts all information about the user: country, region, unique code communication service provider and the code of the device itself. All this information is sent to a remote server via a request, where it is processed and analyzed. This request is then transmitted to the network, and a response is returned to the device in the form of link server information. This connecting server is called a proxy server.

Proxy server (in a broad sense) - link between the user device and the Internet space, a powerful server for processing, analyzing and sending requests and responses to various IP addresses.

The point of using it is that, like the user’s computer, it has its own IP address. Therefore, there are a number of advantages and simplifications in working with the server. In other words, the user does not gain access to the Internet directly, but indirectly - through an intermediary.

Hiding an IP address is a very difficult task for a user. Such a solution may be needed in various situations when it comes to sites that check geographic location or other data about a computer. Or in the case when the user encounters any restrictions on the IP address when trying to enter the site. A proxy server using its own IP provides a way out of a difficult situation. In addition, it eliminates the problem of viewing advertisements and slow traffic loading due to unnecessary content on the Internet, since it simply filters unnecessary advertisements intended for a specific region.

So, the advantages of a proxy server and why the user needs it:

• bypass restrictions related to geographic location;
• access to blocked sites and forums;
• acceleration of network work;
• access to sites blocked by the administrator;
• anonymous use of Internet resources.

In addition, there is a proxy classification: HTTP (one of the most common), Socks, CGI, FTP, etc.

How to set a proxy server

1. In order to set up a proxy on Windows 7, you need to open the “Control Panel”, then select the “Internet Options” sub-item.
2. In the browser properties window, you must select the “Connection” tab.
3. Then step by step select “Network Settings” and check the box “Use a proxy server for local connections" After clicking the “Ok” button, the proxy will be used.

Installing and configuring a proxy also exists for a modem connection. The algorithm for connecting it in this case will look different. First we need to find out the name of the connection with which we will connect to the network. As a rule, it is called a modem that provides communication services. After going to “Internet Options” -> “Connection”, you do not need to select the “Network Settings” sub-item. Having selected the required connection, you should open its settings (right-click) and enter the name of the proxy server and port.

Connecting to an installed proxy server

1. To connect to the installed proxy server, you need to find the “Network and Internet” item and select “Network and Sharing Center”. After configuration, you must also configure the connection from all devices on the local network.
2. Select the item “Change adapter settings”.
3. Right click on required connection to go to its properties. Now we are interested in the “Network” tab, where we select “Internet Protocol Version 4”, then its properties.
4. “Use the following IP address” - left click. We indicate the IP of the computer. Next, you need to specify the network mask, and in the “Default gateway” item we indicate the IP address of the proxy server itself.
5. After confirmation, go to the settings of our browser program and in the “Network settings” field, select the desired item “Use a proxy server for local connections.” We write our address. You can enter the same data in the “Internet Options” of the “Control Panel”.

Having completed the above algorithm, we will receive a configured and ready-to-use connection to the required proxy server.

What to do if the connection does not occur

It is also possible that when correct actions An error occurs during setup or connection. The server refuses to accept the connection, regardless of the user's actions. The malfunction may lie in the line of reception or transmission of information. In this case, you should restart the server, check the client and proxy settings. IN command line You should also enter the “ping” command, which will allow you to check the line at the physical level.

Changing proxy settings

Let's consider a situation where you need to change the proxy server settings in your browser. As you know, there are many browser programs. Therefore, as an example, I will give the most common ones: Google Chrome, Mozilla Firefox and Yandex.Browser.

Google Chrome

The address and other parameters are specified in the “Settings” menu, where you should first select the “Advanced” item, then go directly to “Change proxy server settings”.

Mozilla Firefox

To configure in Firefox browser you need to do similar steps step by step:

1. Go to the Settings menu in your browser.
2. Select the “Advanced” item.
3. Next, open “Connection settings” Firefox connections from the Internet".
4. In the parameters window that opens, enter the required data.

"Yandex.Browser"

You can do the same setup in the Yandex browser. The adapted “Settings” menu will allow the user to quickly navigate in finding the necessary items.

1. Select "Show advanced settings".
2. Find the “Network” section.
3. Click “Change proxy server settings.”

How to find out your proxy server and port

To specify the correct data in the proxy “Settings” field, you must know exactly the required port and server address. To find out this information, you need to refer to the same control panel menu:

Now we determine in which case the user uses a proxy server:

• if there is a checkmark in the “Obtain an IP address automatically” field, then the user does not use a proxy;
• if the checkbox is checked below, next to the active fields that are filled with numbers like 10.0.0.40, then the connection is present, where the first type of numbers is the server.

In the browser properties you can find out the port by selecting “LAN Settings”.

How to disable the proxy server in windows 7

To disconnect from the proxy server, you must perform the above steps and algorithms in reverse order. In other words, the user unchecks all previously checked boxes, resets parameter settings, etc. This can be done either through the toolbar menu or through the browser program.

The proxy server has stopped working

An error or failure in the proxy can occur for various reasons. One of them is installation antivirus program with a network monitoring utility. Or it could be a conflict between the proxy server and the antivirus. This happens because the settings in the antivirus itself are incorrect in relation to the proxy settings outside the program. The same thing can happen when updating a browser program: previously installed settings and parameters are reset, causing a discrepancy and failure of the proxy server. The influence of these factors should be monitored for correct operation proxy on your device.

There is no worldwide network for covert manipulations in space the best remedy than using a proxy server. Skillful and correct handling of it opens up a lot of possibilities for the user. And by studying the intricacies of proxy operation, functions and features, it is possible to increase knowledge from the basic level to the level of the most trivial web programmer.

Many people have heard about the concept of a proxy server. This term is quite common in computer environment. Now we will look at what it is and how to use a proxy server depending on its type. In addition, a basic understanding of preferred settings will be given.

What is a proxy server?

In general, the concept of a proxy server for an uninitiated user, especially in terms of operating principles, may seem quite complicated. Let's try to describe all this in the simplest language.

At its core, a proxy server is a service that acts as an intermediary between the user's computer terminal and resources located on the Internet. Unlike direct connection to resources, in in this case an indirect connection is made, so to speak. First, the user request is transmitted to the proxy, then the information is searched in the cache, and only then the request is transmitted to the appropriate resource with subsequent loading of the information.

However, the question of how to use a proxy server is quite simple, because all operations occur without the participation of the user. Another thing - correct setting. This is what we will talk about now.

Standard proxy server settings in Windows

Let's start with the simplest settings that are made when the computer terminal is first connected to a local network or the Internet.

In the browser settings, you enter the connections menu, where you select the “Network Settings” button. At the bottom there are two fields related to the proxy server. In most cases, these options are disabled, since many providers today simply do not use such servers.

If there is a problem with how to use the proxy server in terms of settings, you first need to enable it, and then enter the preferred address provided by the provider. The default port value is “80”, but it can be easily changed.

In most cases, there is no need to use proxies for local addresses, since they all belong to the same network environment. It goes without saying that all these actions must be performed with the automatic configuration. Otherwise, the specified fields will simply be inactive. In addition, almost the same procedure is provided for those cases in which there is only a modem connection. Only here you will have to specify the name of the connection: for example, the name of the operator servicing the USB modem.

Again, after entering the name, you will need to enter the server address, port, login and password, if provided by the operator.

How to set up and use an Internet proxy server?

On the other hand, in any browser, not just Internet Explorer or its new modification called Edge (Windows 10), you can make similar settings.

So, for example, in Mozilla browser Firefox accesses these features by setting up network connections in the tools menu. First, it is indicated that the proxy will be configured manually, after which the above procedures are repeated. IN Opera browser everything is done by changing the network parameters in the general settings menu.

As is already clear, this applies mainly to free servers, of which you can find a huge number on the Internet. Before you start using it directly from the site, you just need to write down all the configuration data, and then apply them in any Internet browser.

The situation looks interesting when you need to know how to use a proxy server anonymous type. Such services are capable of changing the external IP address of any computer, which allows you to remain “unrecognized” on the Internet, as well as hide traces of your presence there from prying eyes.

As a rule, in most cases there is no need to configure anything here. You just need to go to such a server and that’s it. True, in some cases registration and subsequent authorization may be required, but even if such a procedure is provided, it only takes a few minutes. Most anonymous proxy servers does not impose such conditions, except on servers with increased anonymity. Can also be applied standard settings in browsers indicating all parameters.

Problems and errors

As for situations when a proxy server error occurs, this can mainly only be due to incorrect settings. Here you will have to re-check all the entered parameters, and if necessary, simply change them. And the server itself may, for example, temporarily not work.

Separately, it is worth saying that if the provider does not provide services for using proxy settings, there is no point in trying to change anything, anyway, nothing will get better, or even the connection will be interrupted altogether.
