Proxy servers, which allow Internet users to access websites through one or more intermediaries, help people visit restricted sites at schools, businesses and other locations with monitored or filtered Internet connections. Depending on the speed of your Internet connection and the type of filter you are attempting to bypass, different proxies are available.
What Is a Proxy?
A proxy allows one computer to indirectly contact another. For example, instead of connecting your computer to Website A, you might connect your computer to Computer B, which would connect to Website A and pass the information back to you. Computer B is the proxy.
Many software programs are available that allow you to route Internet traffic through another computer. Mac OS X allows Virtual Private Network (VPN) connections. On a Mac, visit "System Preferences" and hit "Network." Hit the plus icon and select VPN to create a new connection. Many free VPN programs, such as Hamachi, are available for Windows.
Translation services, such as Yahoo's Babelfish and Google Translate, may also act as rudimentary proxies. For example, typing a Web address into Google Translate and translating the site into English will allow you to view the page through Google Translate instead of visiting it directly. The process will fool most Web filters.
Cell Phone Proxy
Phones with Internet tethering services may also be used as proxies on a restricted network. Using a Bluetooth or Wi-Fi connection, many computers allow phones to act as rudimentary routers. By using that connection instead of a school or business-provided connection, a user may be able to circumvent a centralised filtering system. Using a cell phone as a proxy requires significant access to a computer's administrative settings and a data plan allowing tethering.
