Some institutions, such as public Internet access points or schools, install a content filter security device such as SonicWALL on the network that monitors and restricts Internet access. Devices such as SonicWALL often block many sites that do not have harmful content, such as common video sharing sites, social networking sites and even some online e-mail clients. You can bypass the SonicWALL security system by either using a proxy website or proxy server, or by installing a circumventor.
- Skill level:
Open your web browser on the computer that has restricted Internet access and visit the Stupid Censorship webpage (see Resources). This webpage has two proxy services that you can use to bypass the SonicWALL security.
Scroll down to the "PHProxy" section on the page and enter the web address of the site that you wish to access into the "Web Address" field.
Place a checkmark next to "Remove client-side scripting."
Click "Go" to access the site through the proxy website.
Alternatively, enter the web address of the site you wish to visit in the "Glype" section. Glype is another proxy, but is slower than PHProxy. Click "Go" to access the site through Glype.
Open your web browser on the computer that has restricted Internet access and visit the Digital Cybersoft Proxy list for a list of working proxies (see Resources). There is a list of several working proxy IP addresses on the site.
Select any of the available proxy IP addresses on the site. Each of the proxy addresses is a series of numbers separated by periods that resembles "184.108.40.206." A colon and another series of numbers follow each proxy; the series of numbers following the IP address is the associated port.
Click the "Tools" menu and select "Options," if using Firefox. A dialogue box will appear. Click "Advanced" at the top of the dialogue box and select the "Network" tab. Click "Settings." Choose "Manual Proxy Configuration" and input the proxy IP address from the proxy list selected in Step 2. Click "OK." Skip this step if using Internet Explorer.
Click "Tools" and select "Internet Options," if using Internet Explorer. A dialogue box will appear. Click the "Connections" tab and click the "LAN Settings" button. Place a checkmark next to "Use a Proxy Server for Your LAN" and input the proxy IP address into the "Address" field and the numbers after the colon in the "Port" field. Click "OK" to save the settings. Skip this step if using Firefox.
Browse the Internet like usual, using the proxy to bypass the SonicWALL network security device.
Open your web browser on a computer that does not have restricted web access and download ActivePerl, OpenSA 2.0.2 and circumventor-setup.exe (see Resources). Save the files to your desktop.
Double-click "ActivePerl" on your desktop and click "Next." Accept the license agreement, then click "Next" again. Click "Next" three more times, then click "Install." Allow the program to install (the installation may take several minutes), then click "Finish."
Double-click "OpenSA 2.0.2" on your desktop and click "Next." Accept the license agreement, then click "Next." Click "Next" again, then input "opensa.org" into the "Network Domain" field, "www.opensa.org" into the "Server Name" field and "firstname.lastname@example.org" into the "Administrator's Email" field. Click "Next." Select "Complete" and click "Next," then "Install." Click "Finish" once installation is complete.
Double-click "Circumventor-setup.exe" on your desktop, then click the "Unzip" button. A black box will appear; wait while the program installs the necessary set-up files. Once it finishes it will display a URL.
Copy the URL and enter the URL into the browser on the computer that has restricted access. Enter the web address of the site you wish to visit in the "URL" field on the webpage and click "Go" to use the circumventor to access websites. Note that the computer on which you installed the circumventor must stay on while using it on the computer with restricted access.
