Endian Firewall: Open Source Firewall Appliance

This morning I've discovered Endian Firewall. It's an Open Source Firewall Appliance derived from IPCop. The GUI of this OS is very professional and it's integrated all powerful addons on the network. The installation is very simple and post-install configuration is from the web. The most importants Addons of this OS are: Advanced Proxy, ClamAV, Urlfilter and Traffic Control. Here the official community website: http://www.endian.com/en/community/overview/ and the download area http://www.endian.com/en/community/download/.
