Have the administrators of the company where you work blocked the PCs in the office with a firewall, thus preventing you from visiting Facebook, Gmail and other sites that you would love to consult during your breaks? Maybe I can give you a hand.
If you want, I can show you how to bypass the corporate firewall with some free software and Web services that use proxies, that is, remote computers that interpose themselves between the device in use and the Internet sites to be visited, allowing you to visit any external resource despite the limitations imposed by system administrators. It takes more time to illustrate than to use, trust me!
Then? How about putting the chatter aside and immediately starting to get busy? Do you agree? Great! Then let's not delay and proceed. I sincerely hope that in the end you can feel very happy and satisfied with the resources mentioned and that, of course, you will be able to access the sites that you were not able to view before. Happy reading and good luck!
Programs to Bypass the Corporate Firewall
Let's start with programs to bypass the corporate firewall. Below you will find, therefore, indicated and explained what in my humble opinion are the best solutions for Windows e MacOS (as well as for Linux) belonging to the category object of this guide. Put them to the test now and you won't regret it!
UltraSurf (Windows / MacOS / Linux)
The first program I recommend you rely on is UltraSurf, a small but very efficient free software for Windows operating systems and for macOS (as well as for Linux) which, using the special servers, allows you to access portals for which limitations have been imposed locally (but also geographically).
To use it on Windows, go to the program's website and click on the link Ultrasurf (Windows Client) placed at the top, in order to start the download procedure.
Once the download is complete, extract theZIP archive obtained and start the file .exe that you find in it, by double clicking on it. Once this is done, you will immediately see the software window appear on the desktop.
Wait a few moments for the connection to the proxy servers used by UltraSurf (the bars in the main window of the program must turn green) and you will see the window automatically open. Internet Explorer through which you can start surfing the net bypassing the restrictions.
If then on the computer is also installed Google Chrome (for more information, read my tutorial dedicated to the topic) and you prefer to browse online with the latter instead of with IE, click on the relevant icon placed in the upper part of the program window and it's done. Next, the “big G” browser window will open on your desktop and you can use it.
When you want, you can stop browsing with UltraSurf by clicking on the button first Exit in the program window and then on that Close IE/browse and Exit, in order to exit the proxata connection.
I also point out that, if necessary, you can intervene on the program settings by choosing, for example, whether to automatically close the browser window when the program is closed, whether to start UltraSurf but hiding the window, etc. To do this, just press the button Option located on the UltraSurf toolbar.
As for what concerns instead MacOS, first of all, keep in mind that the program works only and exclusively in conjunction with Google Chrome. Having said that, to use UltraSurf you must always visit the software website via the link I have provided you just now, click on the link Ultrasurf (Apple macOS Client) and open the package .dmg which is downloaded to the Mac.
Next, double click on the file UMAC present in the window that has opened and wait a few moments for the del window to open terminal, that the correct commands are given to make the program work and that Chrome is started. After that, you will finally be able to access previously blocked Internet sites through the Google browser window displayed on the screen.
When you want, you can stop using UltraSurf on your Mac by simply closing the terminal e pigging your pulse Ends in response to the notice that will be shown to you.
HTTP Tunnell (Windows)
Another tool you can choose to rely on is HTTP Tunnell, a program available for free for Windows operating systems, through which it is possible to use the SOCKETS servers to navigate on blocked sites on company computers.
To try it, connect to the software download page on SourceForge and click your bottone Download, in order to start downloading. When the download is complete open, by double clicking on it, the file .exe just got it and click on Run.
In the window that is now shown on the desktop, click on the button Next twice in a row and on buttons install, Si e Finsh to finish the installation process. Now, search the Start menu the link HTTPTunnel Client and click on it. If a window relating to the Windows firewall opens, click on the button Allow access to grant the program the permissions it needs to function properly.
At this point, you should finally be able to access the internet without restrictions. To be sure, try visiting one of the sites that you previously couldn't access. When you want to, you can stop using the program by right-clicking on its icon that has been added to the notification area and selecting, from the menu that opens, the option Close HTTPTunnel Client.
If, on the other hand, you need to make changes to how HTTP Tunnell works, select the option Settings from the menu that opens after right clicking on the software icon in the notification area and intervening on the items attached to the browser page that will open. From there, you can change the port mapping, the settings relating to the HTTPTunnel server, the status of the service and so on.
Freegate it is a program that works almost similar to UltraSurf, of a portable nature and able to circumvent any impediment while surfing the Net dictated by the use of a corporate firewall. It's free and compatible with Windows only.
You ask me how to use it on your PC? I'll tell you right away: first, go to the software website, click on the link Download the latest Freegate client software and on that download exe in the new page that opens, in order to start the download.
When the download is complete, open, by double clicking on it, the file .exe just got it, presses the button I Agree in the window that opens on the desktop, select the option All website go through Fregate proxy and click the button OK. If you see a warning about the Windows firewall and the use of Freegate, click the button Allow access.
At this point, you can start surfing the Net by going around the blocks imposed by the corporate firewall, using the Internet Explorer which in the meantime has opened on the desktop. When you want to, you can stop using Freegate by clicking on the button Turn OFF in the program window on the screen. Then confirm your intentions by pressing the button Yes and it's done.
To access the Freegate settings instead to choose, for example, whether to start the program when Windows starts, whether to delete the browser history when the program is closed, etc., click on the button Settings that you always find in the software window, at the top.
Online Services to Bypass the Corporate Firewall
You do not want or can not download new programs on your computer and would you therefore be interested in understanding if there is any tool available directly online, regardless of the operating system used and the browser, to bypass the corporate firewall? Then put the i to the test now web services specifically used for the purpose you find below.
The first of the online services used for the purpose of this tutorial that I recommend you use is Zend2: it is a Web proxy that allows you to browse any Internet site bypassing the corporate firewall. It's free, requires no registration and is very easy to use.
To use it, connected to its home page, type the address of the Internet site you want to visit in the field in the center of the page and click on the orange button Surfing. In a few moments, you will finally be able to access the site that was previously blocked. It was simple, wasn't it?
If necessary, before starting navigation, you can click on the entry Options under the search bar and adjust the settings related to the operation of the service as you see fit, leaving or removing the check marks from the various items.
Another great online service useful for bypassing the corporate firewall is HidesterThis is an online proxy that works similar to that of Zend2. It's free (in its basic form) and it's also fairly fast. Personally, I suggest you put it to the test immediately.
To use it, connect to its home page and fill in the field Enter URL located in the center with the web address of the website you wish to visit. Subsequently, click on the drop-down menu located on the left and select the server you want to use (and therefore the country of reference and of which you intend to acquire the IP), then presses the button Browse anonymously placed in the center.
If you want, before starting to navigate to a specific site, you can use the drop-down menu on the right side of the service page to adjust the navigation settings based on your preferences and needs.
To conclude, I want to report you ProxySite: it is one of the most famous online services in the category covered by this post. Similarly to the other solutions I have already told you about, it is free (but you can possibly further enhance it by opting for one of the paid solutions available) and allows you to surf the Net behind proxy servers, bypassing the restrictions applied locally as well as regionally. Note that the interface is very nice and is translated into Italian.
To use it, connect to the home page of the service and choose the server you want to use via the drop-down menu on the left, then type in the field Enter Url adjacent to the complete address of the website you want to access. Finally, click on the button vai, wait a few moments and you will finally find yourself in front of the Internet site that you previously could not visit.
Then I would like to point out that in the ProxySite home there are also buttons that, if pressed, allow you to instantly access some of the most used online services of the moment, such as Facebook and Twitter. If, on the other hand, you need to adjust the settings for using the service, click on the wording Settings placed at the top of the main page of ProxySite and intervene on the available options according to your needs. To apply your changes, remember to click on the button Save.
