This project will serve as a central hosting/bug tracking center for modifications to the SmoothWall.org firewall distribution. Support and information for the "mods" posted here can be found on the SmoothWall.org forums, the SmoothWall.org IRC server, or

CacheGuard-OS, amongst other functions, embeds a Web Gateway allowing you to have control over what type of Web content is allowed in your organization, by whom and when. The Web Gateway works as a transparent or explicit Web proxy and blocks malware and other unwanted contents such as ads or adult websites at gateway even in an encrypted format (HTTPS). In addition, its caching capability allows you to cache bandwidth-intensive traffic such as YouTube or Windows updates in order to save your bandwidth. CacheGuard Web Gateway is distributed as an open source OS called CacheGuard-OS that you can install on a virtual or hardware machine of your choice. Once installed on a machine, CacheGuard-OS transforms that machine into a network appliance. In addition to the Web Gateway, CacheGuard-OS includes multitude of other services such as VPN, WAF and WAN optimization. CacheGuard products are especially designed to address SME requirements by providing functional solutions.

Debian packages for PeerGuardian Linux (including the GUI) and its precessor moblock/blockcontrol/mobloquer. PeerGuardian is a privacy oriented firewall application.
