What is Endian Firewall Community?
Endian Firewall Community is a "turn-key" linux security distribution that turns every system into a full featured security appliance. The software has been designed with "usability in mind" and is very easy to install, use and manage, without losing its flexibility.
The features include a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, FTP, POP3, SMTP) with antivirus support, virus and spamfiltering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on OpenVPN). The main advantage of Endian Firewall is that it is a pure "Open Source" solution
