IP Filter

IP Filter is a TCP/IP packet filter suitable for use in a firewall environment. To use, it can either be run as a loadable kernel module (recommended) or incorporated into your kernel. Scripts are provided to install and patch system files as required. IP Filter also supports transparent proxying via packet forwarding, including round-robin forwarding to achieve load-balanced proxy.
