Select a web filter to install on your server. Filters such as Safe Squid, Wingate or Guardian Web Filter will identify proxy servers that attempt to identify your network, and will process those requests according to your instructions. Content filters, such as Allegro Surf, can also be used, by setting them to block the word 'proxy.'
Verify that your web filter is compatible with your operating software. Note that if your operating system is newer than the one required by the product, you will be able to use it; problems will occur, however, if you attempt to run a new product on an outdated operating system.
Install the software to your computer and select your options for how to process connections. Click on the option which checks the direct web access or use the firewall to allow only certain known sites. In the 'Web Filters' tab, enter names of the web pages that you want to block or ban. You can also name specific websites that you use for browsing. This prevents unwanted websites from hacking your information. It also stops redundant applications from downloading into your system.
