Using a proxy server for local connections. How to set up an anonymous proxy server

A proxy server is a service that is located on a local PC or a remote host. This tool performs following functions: filters traffic and ensures its security, guarantees anonymity when visiting sites, increases the speed of information transfer and much more. Sometimes a system connecting to a network through a proxy . In this article, we will look at why the message “Check your proxy server and firewall settings” appears in such situations and what the user needs to do to resolve the error.

Message about the need to check settings

Finding a solution to the problem “Check your proxy server and firewall settings” depends on whether the user accesses the network through a proxy or not. By functional features intermediate servers can be divided into two types: web servers and applications installed on a PC. If the connection is made through an application (Kerio or Squid), then you need to check whether the settings are lost. If you access the network using remote proxy resources, there are two options for solving the problem:

• view the list of available intermediary servers;
• make sure the proxy port is in at the moment is not busy with another task, causing the service to be temporarily blocked.

To certify normal operation PC access the network via proxy from another computer. If the message “Check your proxy server and firewall settings” also appears, then take the following steps.

Similar errors:

Step 1: Disable the proxy server

The first thing you can try is to disable the proxy server, although this will be quite painful for the user. The method is called painful because access to the network will remain and sites will load, but not all resources will be accessible, but only those that do not work through an intermediate server. The rest will remain blocked. You can disable the proxy in the settings of the browser you use to access the Internet. Of course, the settings menu looks different in each browser, but in general terms the process can be described as follows:

Proxy data

Step 2: Setting up a broker

A more effective method is to configure a proxy server. Let's consider this process. Lists of free intermediary servers available for a specific country are posted online. What do you need to do?

Entering IP addresses and port numbers

• restart the browser (in our case it is Yandex).

Now you can check your IP address using one of the services. It will determine that you are accessing the network not from your computer, but from the IP changed in the settings. But in in this case there will be no data about the OS and host used, and information about your location will be unreliable.

What to do if a proxy server is not used to connect to the network

If a proxy is not used to connect to the Internet, and the “Check your proxy and firewall settings” message still appears, try the following:

• make sure that the Internet is working normally (if necessary, restart the modem/router or even disconnect it from the power supply for a while);
• perform a normal reboot of the computer - perhaps the system is simply “tired” and needs a short rest;
• open the site from another computer - there may be errors in the operation of the resource or your provider;
• go to the web page from another browser - maybe the browser is not functioning correctly and you need to reconfigure it or reinstall it;
• check whether the site is blocked by an antivirus that has detected a security threat (usually the program displays a message about this).

If these steps do not help, try the following. It may be that the site developers changed the IP, and the PC is trying to contact the resource at the old address. In this case, open command line and enter the command ipconfig /flushdns (since the problem may be with the DNS settings).

Entering ipconfig /flushdns at the command line

When using embedded software that protects the PC from various threats - firewalls, firewalls, firewalls– review the settings, as such programs can block access to sites on the blacklist.

Here's what you can do regular user, if collides with system message“Check your proxy and firewall settings.”

Basic methods for setting up proxies in browsers, operating systems, proxies, various programs and browser extensions

A proxy server is equipment connected to the global network that is rented out or randomly opened to interested users. Speaking in simple language By connecting to a proxy, you can log into the Network through a different IP address without leaving a digital trace.

Today, access to proxy servers is offered by many providers as a separate service, which allows users to access blocked sites or use several accounts simultaneously without fear of being banned or blocked.

Correctly setting up a proxy server largely depends on the purposes for which you are going to use free access through another IP. If the selected server is used only to access prohibited sites, then it is enough to make a few changes in the browser itself, and the Internet will open to the user in all its glory. However, if a proxy server is used for work, and even more so if there are several such servers, then a serious reconfiguration of the operating system itself or the installation of additional software will be required. Let's look at all the options on how to set up a proxy on your computer for comfortable and fruitful work.

How to set up a proxy in the browser

Proper proxy settings will allow you to use access to sites on maximum speed connections and will make your work on the Internet much easier. The procedure for setting up a browser for a proxy is as follows:

Taking a closer look, you will notice that the proxy configuration path is virtually identical in all browsers. This list can be supplemented by Yandex.Browser, but the way to connect the proxy server itself will remain unchanged - the main thing to remember is that you need to change the parameters for connecting to the Network, and then move intuitively, fortunately the developers have tried to simplify this task as much as possible.

Setting up a proxy in the operating system

Users who intend to constantly surf the Internet through a proxy server can make their own lives easier by redirecting in advance network connection in the most operating system. This is done as follows:

• 

  
  Before connecting a proxy server in Windows OS, it is important to remember that when connecting such remote access, you are making changes to the properties of the Network, which means this is what you need to look for. By opening the Control Panel window, you will find the browser properties, where you need to make changes. Select “Connections” and then “Network Settings”. Then you need to give permission to use the proxy server and enter the initial data, that is, the address and port number.

• 

  
  The main advantage of this operating system is its intuitive accessibility, so making changes to the connection settings is quite easy: In the additional system settings, you need to find the “Proxy Settings” itself, which you need to change. In the window that opens, enter the IP address, port, as well as login and password, then click on the small padlock at the bottom that allows changes, then click “Ok”.
• Linux

  

  
  The task is how to enable a proxy server in the operating room Linux system, will be quite simple if you understand configuration files or you don’t need to use a password and login to connect a proxy. Essentially, the configuration path is as follows: To configure configuration files, it would be best to use special utilities;
  • IN system parameters you need to find the “Network” section.
  • Then go to the proxy service and manually change the connection configuration, that is, register the proxy data.
• OS Android

  

  
  There are two ways to install a proxy server on Android.

  First- through the application when Root help(administrator rights). After installing the desired application (like ProxyDroid), enter the proxy address and port, and then activate automatic connection.

  Does not assume using Root, and you need to do the following:

  • Find the “Advanced” item in the network settings.
  • Convert settings to manual mode.
  • Next, enter the server data and connect to the Internet.

• 

  
  Set up a connection via a proxy server in iOS system you can do this as follows: in the settings, select the Wi-Fi section and find the network to which the device is connected. Scrolling to the very bottom of the section, you will find the HTTP proxy option, which is disabled by default. Switch the settings to manual mode and enter the IP address and port number of the proxy in the “Server” and “Port” lines. Then log in and authenticate. Now Apple iPhone will access the Internet through the server specified by the owner.

Correctly installed proxy server will provide round-the-clock access to any web resources.

Setting up a proxy server using a proxy

Proxifiers - a separate type of software that simplifies working with proxy servers. In order not to ask each time the question of how to install a proxy, programs and applications have been developed, such as Proxy Switcher, Frigate or. The Proxy Switcher functional extension makes it much easier to work with a proxy server, allowing you to anonymously visit sites.

Setting up a proxy server through the application is easy:

• In the browser menu, select “Add-ons”;
• Enter the name into the search bar desired application;
• Add the selected application to the browser;
• After activating the application, select manual settings;
• Enter your proxy information and select required protocol connections;
• Having saved the entered data, you create profile No. 1;
• By repeating the procedure, you can create several profiles, switching between them with a simple click mice.

Naturally, each proxy has its own characteristics, but in general the process of setting up such programs and applications is very similar. The only difference between software like Proxifier and browser applications is that special software works much easier with a large number proxy, using the power of the OS. Therefore, if the user is going to use dozens or even hundreds of servers daily for arbitration, SMM promotion or gambling, it will be more convenient for him to install separate program which will make his work easier.

Today, most Internet programs are created or reformatted to be used via a proxy. Such popular methods of making money on the Internet as parsing, arbitrage or SMM promotion require the simultaneous use of several dozen or even hundreds of accounts, and therefore special software, which will help simplify this process.

As an example of setting up proxy servers directly in programs, let's take the popular parsing software -:

• Specify the required passwords and logins in your account settings;
• In the “Network” section, check the box in front of the “Use proxy servers” line;
• Add to the list the addresses and ports of the servers that you plan to use;
• Click “Check in...” After parsing, be sure to check the log and make sure there are no errors in it;
• In case incorrect operation clean your computer of temporary files, cookies and other things digital trash, which may cause your account to be blocked.

As you can see, installing proxy servers for working in this program is extremely simple, and therefore very profitable, because connecting such software speeds up the process of data analysis.

Useful browser extensions for working with proxies

Browser application developers have not ignored the growing percentage of using proxy servers to bypass regional blocking of web resources. The most popular applications for working with remote access to the Internet are FriGate and Proxy Switcher.

Setting up these applications is accessible even to a novice user. Main feature working with a proxy through these applications is that the user can connect not only several servers, but also configure access through them only for certain sites. Simply put, if the proxy server is only used to log into social media, then a separate address is indicated in a separate settings column and only this web resource is launched via remote access, while all others work through the user’s IP.

Which proxies are the easiest to work with?

A separate topic of discussion on the Internet is whether it is worth buying a proxy or is it better to use free options? There is no single answer to this question, because it directly depends on the circumstances and purpose of using the proxy server.

Free servers are convenient due to the lack of financial costs, but that’s where their advantages end. If a user uses such a proxy once a day to log into his own page on a social network, then he will not feel any particular inconvenience, but they are not suitable for serious work on the Internet. By deciding to connect a proxy server for free, you risk your own confidential data, because besides you, this equipment will definitely be used by hundreds of other people, and who knows what thoughts drive these masses. Besides, free equipment can turn off at any time.

Having decided, the user receives comprehensive support from the seller, ranging from assistance in setting up and ending with the replacement of a non-working server. The cost of one unit is not so high as to feel a serious blow to the budget, but the profit that you can get from serious work through a paid proxy can really please you.

By purchasing one single or a whole package of proxy servers, you get a guarantee of a high-quality connection and fast response of the desired web resource, which makes the use of such Internet access truly effective means earnings. Ultimately, the end justifies the means. Therefore, if your goal is minimal surfing on the Internet and visiting own account on a social network, you can use free connection options. But if you want to earn serious money on the Internet, then it is best to buy yourself a couple of reliable proxy servers, setting up and working with which will not be a problem for you.

Lifehacker has already talked about how to buy virtual server(VPS) and to bypass Internet blocks. But VPN works for all programs that have Internet access. If you want traffic to be redirected to another server in the browser only, create your own .

Considering the ban on anonymizers and VPNs, which may begin to be applied in practice at any time, having your own proxy server will guarantee your freedom on the Internet.

How to create a proxy

How to choose and buy a VPS is described in detail in the material on raising a VPN. Let's not repeat ourselves and move straight to setting up a proxy server.

How to run a proxy on individual sites

To use the proxy server only on certain sites, install the FoxyProxy extension in your browser.

Open the extension settings and click Add New Proxy. On the Proxy Details tab, enter the IP address and port number that you previously specified in Putty. Check the SOCKS Proxy option.

Go to the URL Patterns tab and add masks for the sites where proxies should be used. To add a site mask, click Add New Patterns, enter its address with asterisks on both sides: for example, *site.com*.

When the proxy extension is enabled, only those sites whose masks you included in the list will be displayed. The remaining addresses will open without a proxy.

You can not create a list in FoxyProxy, but use the “ ” extension. It contains a list of “Anti-censorship”, which covers most of the sites blocked in Russia.

Click on the extension icon on the taskbar and open the “Custom proxies” tab. Check the “Use YOUR OWN proxy” option, enter the IP address and port number.

How to save a session

In order for the proxy to work, you must always have a Putty session running. You can save your settings so that all you have to do to connect is enter your password.

Launch Putty. Set up the connection as shown above and go to the Data tab in the Connection section. Enter a name for automatic authorization: usually it is root, but the hoster can assign something else in the letter.

Go to the Session tab, enter any name in the Saved Sessions field and click Save.

Your connection will be saved in the list of sessions.

The next time you start Putty, select it, click Load, then Open to establish a connection and enter the password from the server that the hoster sent in the letter.

A local proxy is necessary so that one of the clients can contact another, but not directly, but through third party computer. Typically, an appeal follows a predetermined algorithm.

First, a person contacts the server, saying that he wants to open, for example, a website. When responding to a request, the server independently accesses this site. After that it returns the results. In this way, “distributing the Internet” from one computer to another is realized.

Setting up a local proxy in steps

To get started, you need a proxy. Can be found free analogue or . If you need a large local network, then it is better to purchase the address of a stable computer. Free options are quite unreliable, and you can’t count on full technical support and normal speed of work.

To configure a proxy you need to take the following steps:

1. Buy a proxy server address.
2. Allow the Internet to be distributed.
3. Set up a proxy.

The first point is clear. Let's explain the other two in more detail:

This completes the simplest settings for the local proxy server. All computers in your local network will be able to connect to you and gain access to the necessary resources.

If necessary, in the router settings you can open the port that the proxy server uses.

If necessary, you can do more subtle configuration. For example, you can configure access to the server by setting a login, password and adjusting the authorization system. You can create your own database by encrypting it.

However, all these features are only available with the optional software. Find good programs you can with the help of our blog.

A proxy server provides an opportunity for unhindered and secure access to content, especially in cases where the provider has blocked access to it. A proxy server is also considered as a gateway, ensuring the flow of information data simultaneously in both directions: from the user to the network resource.

Those who engage in active surfing seek to find recommendations on how to use a proxy server, as this allows the requested Internet pages to load faster and also guarantees the user absolute anonymity. No wonder translated from English language the word “proxy” means use on behalf of someone else.

However, most users still do not understand why a proxy server is needed or what the benefits of using it are. Every PC that goes into Global network, accompanied by . Knowing it, it is enough to simply calculate where exactly the user lives, which specific provider provides him with Internet services. If it is important to hide personal data, all requests should be made through a proxy acting as an intermediary. In this case, the IP address of someone other than the one working in the world wide web, and the proxy used.

Purpose of a proxy

The proxy server is capable of performing several useful functions, attracting the attention of users. In addition to providing complete anonymity, the proxy successfully caches Internet pages, which in the future allows you to speed up the process of opening them, while at the same time ensuring economical use of Internet traffic.

Another successful proxy function is the real ability to secure personal computer user from possible network attacks. Some enterprises interested in working securely with Internet resources prefer to use proxies, as this guarantees the protection of important data from hacking by intruders.

Also, some people prefer to use it due to the fact that it allows successful anonymous surfing.

Manually setting up a proxy server

To take advantage of the unique features of a proxy, you need to understand how to configure a proxy server. Everyone can use its capabilities only after he manages to find suitable option, check its functionality, and then provide quick access to it.

The proxy server is configured in two modes: manual and automatic. Manual method is not so welcomed by users, since they have to independently search, then check the selected options for functionality, and after successfully passing the test, they also have to make changes to the browser themselves.

To make the appropriate changes to Mozilla browser Firefox, you need to go from the “Settings” menu to the “Settings” item, and then to the “Advanced” tab. Next, among the list additional features you should select the line “Network”, click on it and in the window that opens, check the box opposite the line “ Manual setting proxy service." All that remains is to enter the data, after which contact with the proxy will be established.

Setting up the Opera browser is almost identical: from the “Settings” menu, go to the “ General settings", then "Network", and then "Proxies".

Browser Internet Explorer It’s also quite easy to set up after going to the following menu items: “Tools”, “Internet Options”, “Connections”, “Network Settings”. To enter data, just check the box next to the “Use proxy server” line.

IN Chrome browser it is also quite simple to make changes to the proxy server settings. You need to click on the “Tools” item, go to the “Show” tab additional settings", and then select "Change proxy settings".

Automatic setup

Setting in automatic mode involves the use software, facilitating the ability to quickly find and automatic selection optimal proxy.

Currently, developers offer a sufficient number of useful software tools that allow not only automatic search suitable resources, but also automatic check them for functionality, followed by instant integration into the appropriate browser.

Such software tools include:

• Mask Surf;
• Proxy Switcher Pro;
• Proxyassistant;
• Hide IP Easy.

If the question arises of how to change the proxy server, the user can easily figure it out this issue. In most cases, the interfaces of these software tools are Russified and are also quite understandable to every user, so it will not be difficult to change IP addresses with simple clicks.

Disabling a proxy server

In some cases, it becomes necessary, on the contrary, to eliminate existing contact with the proxy server; in this regard, it is useful to understand how to disable the proxy server if it acts as an obstacle to achieving specific goals.

Disablement rules

Unfortunately, some free proxies are subject to blocking, due to which it is not possible to open pages important to the user. In this regard, it becomes necessary to disable proxy functions in order to change the IP address, thereby ensuring access to selected resources.

To disable the proxy, you need to go into the browser settings in the same way as when connecting it, after which you should uncheck the box next to the line indicating the activation of this function.

After such actions have been taken, you can again use the original network settings, open the necessary Internet pages, but all transitions will be under the supervision of the provider.

So, change network settings anyone who feels an urgent need for it can. It is enough to select an acceptable option for searching and checking the functionality of the proxy server, and then test all its capabilities in practice.
