Firewall Bypassing

Bypass a Firewall or Internet Filter
Don't you hate it when you go to a website at school and find out that the school web filter blocks it? This guide will teach you multiple ways to bypass the web filter to access your websites. Some methods only work with certain filter configurations so you may have to experiment with several methods to find the best one for your situation.

 Steps


Browse Using UltraSurf or JonDo

Both programs use the self-invented GIFT system with a high-encryption standard. GIFT is a node-proxy anti-jamming system that claims to have higher standards than financial transaction industry security.
  1. Download the Ultrasurf or JonDo client software. Both can be downloaded in exe format.
  2. Unzip the software using either PeaZip, Winzip, or WinRAR.
  3. Once unzipped, run the program. Ultrasurf and JonDo are green software and don't require installation. Simply execute U[version].exe example: U86.exe, U87.exe or JonDo.exe. The software will try to connect to proxy servers and will open a default web page in your default browser upon successful connection. The software will work on any installed browsers.
  4. Put the executable on a flash drive at home. It can then be run off the flash drive at school if you are unable to download it while at school.
    • Important: Use these programs very discretely. If work or school authorities discover what you're doing, they will undoubtedly disable the computer system from being used in the future.
    • Keep in mind that some networks only allow authorised programs (exe's). Using separate programs listed above will not work.
  5. Note that if both of these clients are blocked, others can be found below.

Browsing by Proxy

  1. Join a mailing list. Since proxies get blocked often you should join a proxy mailing list like Circumventer (link below), to keep getting fresh proxies daily.
  2. Find a proxy site. Do a search for "free online proxies". This will provide you with a list of proxies to bypass filters, such as FrogTunnel or Vtunnel (requires JavaScript).
  3. Find a proxy site that is not blocked by the filters.
  4. Type the name of the site you want to access into the box. Most sites have a checkbox that says "block scripts"; it is better to uncheck this.
  5. If none of these work, download and install Firefox and manually change the proxy settings. Go to Tools > Options > Connection Settings, and change the Proxy Settings to a proxy. Go to ask.com and search proxy lists.
    • If your school blocks a certain proxy, there is a way to access it. Get the URL via Google and then click on "cached." This will enable you display the page and use the proxy. Keep in mind that adaptive firewalls will catch you and permanently block the site. Another way to get around a firewall is to put spaces between letters when searching for sites. Like this: p r o x y . a b c 1 2 3 . c o m

Use a VPN if Proxy sites don't Work

  1. A VPN works as an encryption agent between your system and network and in this way it bypasses all firewall restrictions. You can download a VPN software or setup a manual virtual private network on your own system by using details provided by vpn provider. A free VPN is best choice to unblock websites at school computers.
  2. Hotspot Shield, SuperVPN and Open VPN are some popular names from vpn providers. You can download a free VPN from http://www.unblock-gamesatschool.com to unblock games websites and firewall filters at your school.
  3. Just install and click connect, Now you can access all blocked content at your school.

Hosting a PHP Proxy

  1. Find a free PHP host like Bravenet on an unblocked computer. Make sure it has FTP Support or a way to upload PHP scripts. Create an account.
  2. On an unblocked computer, find a PHP Proxy script. There are many available and is usually just one file.
  3. Upload the PHP Proxy script to your PHP host. Test it by executing the script from your browser.
  4. Type in the address of your script into your school computer.
  5. As an example: If you went to Bravenet, your host might be youngone.bravenet.com. Upload your proxy i.e. "snake.php", and execute it by going to "youngone.bravenet.com/snake.php". That's it.
    • If you create a PHP Proxy, use a different name. Do not create a host called "mycoolproxy.phphost.com/hacker-proxy.php"

Browsing via Remote Access

  1. Leave a computer on and connected to the Internet at home. Enable remote access.
  2. Set up remote access on your school computer. Go to Start -> Accessories -> Remote Desktop Connection. Put in your IP address (or sign up your computer at home for dyndns.org to get a name for it if your address changes all the time). You can connect to your home computer, and do anything you want from there.
  3. You can also use a VNC service.
