How to check proxy server and firewall settings. Illustrated tutorial on Adobe Dreamweaver MX

Internet users often have a desire to hide their IP address. This raises the question: “proxy?” This can be done “manually”, i.e. you can set up a proxy server in your browser yourself or use special Proxy programs that can independently find a working proxy server and integrate it into your browser.

If you choose the first method, you are likely to encounter a number of problems that complicate your work when searching for proxy lists and checking their performance, because many proxies are not working.

The second way to solve the problem “how to set up a proxy” is much simpler for a beginner, but it should be taken into account that some programs are paid and they are most often in English.

Setting up a proxy manually

To configure a proxy manually, you need to go through three steps:

find proxy lists (lists of proxy servers on websites);

integrate them into a proxy on your browser);

check the proxy for functionality (using special sites).

Proxy lists are posted publicly on the network, which can be easily found by a search engine by requesting a search for free proxy lists or “free proxy”.

The proposed list does not always contain only working proxy servers, so the site with the found list always offers a function for checking them, which helps to weed out the “dead” ones, but this is also not a 100% guarantee.

Checking such servers on the site ends with the formation of a table with the results of the check.

Analyzing it allows you to choose a suitable proxy server. When viewing the table, you should pay attention to whether the proxy is also hiding the IP. If not, then we discard this option.

Now we need to install a proxy server in our browser. There are differences in setting up proxy servers for different browsers.

Setting up proxy servers in Internet Explorer

Select the first working proxy from the list.

1. Having opened Internet Explorer, through the “Tools” panel (at the top) go to “Internet Options”.

2. Going to the “Connections” tab and selecting ours (in this case “internet”), go to “Settings”.

3. In the new window, select “Use a proxy server for this connection” by checking the box. After this, the “Port” and “Address” fields are activated. From the selected proxy, insert the last 4 digits into the “Port”, and all the rest, respectively, into the “Address”.

Setting up proxy servers in Mozilla FireFox

1. Open Mozilla FireFox and go to “Tools” (top panel), select the “Settings...” tab.

2. Then select the “Network” tab and click “Configure...”.

3. After the “Connection Settings” window opens, check the “Manual configuration of the Proxy service” checkbox. Clicking activates the “HTTP Proxy” field and the “Port” field. We enter “HTTP and Port” from the selected proxy.

All changes have been completed, including leaving the “Do not use proxy for:” column as default.

After clicking “Ok”, the proxy setup will be completed.

Setting up proxy servers in Opera

1. Open Opera, go through the “Tools” panel to “Settings...”.

2. Then go to “Advanced”, after which a menu will appear on the left, where you need to select the “Network” section and click “Proxy servers…” in it.

3. In the new “Proxy Servers” window, check the box next to “HTTP” and enter “HTTP” and “Port”.

Checking the functionality of the selected proxy server

After the proxy setup in the selected browser is completed, save the change and go to any site for checking the location and IP address.

If the page does not load, it means the proxy is not working. We configure the next proxy from the proxy list.

If the page displays your city, it means something was done wrong or the proxy is “dead”.

If the page does not display your city, it means that you did an excellent job with the task of setting up a proxy.

To disable the proxy, you need to uncheck the box in the settings of the selected browser about choosing a proxy server.

Programs for accessing a proxy server

Programs have been developed for anonymous surfing. The most popular programs for solving the problem “How to set up a proxy” are Mask Surf, Proxyassistant, ProxySwitcherStandard. Their use greatly facilitates the search for a list of proxy lists, reduces the time spent on checking and integrating the found proxy into the browser.

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, 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 that are capable of using a large number of proxies in their 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 context menu item "Switch to this Server".

  

• If you need to add your data, click the red plus button on the top toolbar.

  

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 (text file) with addresses, ports and authorization data (see above), then you can load it 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 force only a specific program to work 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 the executable file of the program or game on the disk 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

Configuring system network settings allows you to route all traffic, both incoming and outgoing, through the 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 be content with system settings, application (browser) settings or extensions. All options give the same result, only the time spent entering data and additional functionality changes.

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 on which the desired resource is located (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. Read more about setting up a proxy server in Windows 7 in 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 settings” if you are connected via a local network cable or Wi-Fi, or “Configuring 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”. Click on the 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 on a home or corporate network, and a proxy server is configured on another computer on the network, then the tracert system command will help you. 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:

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, its throughput will be significantly reduced: and it will take longer to load data onto the 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.

Setting up a Windows 7 proxy server is a prerequisite for playing games or performing daily work related to the Internet. Today we will reveal the secret of how to properly configure a proxy server on Windows 7. If you follow simple instructions, you will definitely succeed!

In our age of information technology, when the level of security on the Internet decreases every day, and the use of a proxy becomes the “cornerstone” in keeping personal data intact, the issue of protecting the corporate network of an enterprise remains relevant if it is directly tied to IT. Proxies are indispensable for performing analysis and data collection tasks (so-called parsing) on ​​some social networks (for example, VKontakte) and for bypassing regional bans on certain resources.

Almost every proxy server for Windows 7 can be configured both by special utilities and by the Windows OS itself. Let's look at one of the popular ways to configure a proxy server using Windows OS.

Step by step instructions

So, first, go to the “Control Panel”, which can be found in the “Start” menu. Next, you need to select the “Internet Options” sub-item (or “Internet Options” in Windows 8.1).

In the open window, go to “Connections”, find “Network settings” and boldly click.

Below you need to enter the address and working port of the specified proxy, and then next to the proxy working port input field, click “advanced”. In the window that opens, select the “one proxy for protocols” option. After completing the procedures and manipulating the settings, when loading any browser, a “login-password” entry window will appear for the proxy you specified in the settings. If you set authorization by IP, then no additional data entry is required.

If, as a result of the steps taken, something went wrong, repeat all the steps according to these instructions. Perhaps something was missed somewhere. If you need, then take into account the fact that although the actions are similar, there are still differences.

Using a proxy server allows you to solve many very useful tasks for the user, including ensuring secure traffic, ensuring anonymity on the network, filtering traffic, etc. A proxy server is a utility application hosted on a remote host (or ) that makes indirect requests to the target web server.

Unfortunately, incorrect settings in a web browser running through a proxy often cause the system to fail to connect to the proxy server. In this case, instead of the user’s favorite site, he is greeted with a system error message with the text “check your proxy server and firewall settings.”

Partially, this issue has already been discussed in the article, but here we will tell you what to do if the proxy server refuses to accept connections.

The proxy server does not respond: what should I do?

Currently, there are many types of different proxy servers.

However, depending on the functionality, all proxies can be classified into:

• - proxies in the form of separate applications;
• - web services.

The algorithm of actions to eliminate a failure when connecting to a proxy server directly depends on the “type” of the program.

• - It is quite possible that the browser is using the parameters of one of the remote web services - in this case, you need to look at the available lists of proxy servers.
• - If a proxy server application (Squid or Kerio) is installed on your local PC, then first of all you should check that the program settings are correct.
• - Also, when connecting to a proxy, it is possible that the port used by the local proxy server is already occupied by another process - accordingly, the operation of this service is temporarily blocked. Thus, when a failure occurs, the first thing you need to do is check whether the proxy server port is busy.

Let's note one important nuance: when the proxy server refuses to accept connections, in fact, everything may be fine with access to the Internet. For example, Skype or other network applications work fine, it updates its database, etc.

How to disable the proxy server in Windows 7?

Obviously, the first effective, but not the most successful solution would be to disable the proxy server in the web browser settings. It should be understood that if you disable the proxy, Internet access will be restored, but all web resources working through the proxy server will be blocked.

If you nevertheless decide to eliminate the proxy server error through “surgical intervention,” then you can disable the proxy in the settings of the browser you are using.

At the same time, each browser has its own “subtleties”, so we will note here only the basic principles using Mozilla as an example.

• - Find the settings option.

• - Go to the "Advanced" tab.
• - Find the “Network” section.
• - In the “Connection” column, click the “Configure” button.

• - Delete the address and port of the system-assigned proxy server. (By the way, you can find out the address of the proxy server used and the port here)

• - Set, for example, the option to use the system proxy settings.

How to check and change proxy server settings?

A much more effective solution would be to use the right to configure your web browser to work through a proxy service. To do this you will need to do a few basic steps:

• - Search the global network for lists of available free proxy servers.
• - Filter them by country and determine the server closest to you that supports the protocol you need: HTTP, HTTPS, Socks4 or 5.
• - Write down the suggested IP address and port.
• - Open your web browser settings and go to the Network section. Here, open the connection parameters window by clicking the “Configure” button.
• - Enter the recorded data in the appropriate fields of the corresponding protocol.

• - Restart your browser.

If you use, for example, a Socks4 proxy, then this verification service will show you that the request is not made from your PC, but from the IP address of the proxy server.

However, this service will not be able to provide information about the type of operating system, host, and your location data will also be distorted.
