I stumbled on the Sphirewall Project the other day. Sphirewall is an open-source Linux firewall to compete with Iptables, Smoothwall and Monowall. The following are excerpts of the Sphirewall website.
Sphirewall is an open-source Linux firewall and router that provides advance user management and bandwidth analytics coupled with powerful flexibility. It’s open-source, free, easy to install and built from the ground up not using iptables.
Check out the features below
- Full NAT/PAT and ip filtering support
- User authentication and group based filtering
- Detailed analytics and reporting on network traffic
- Web, commandline and json api based management
You can download the debian iso, burn it to a cd, usb stick or mount it in your favorite virtualization system and get it running in minutes.
