shorewall-lite - 5.2.3.4-1 main

Shorewall allows you to describe your firewall/gateway requirements using
entries in a set of configuration files. It reads those configuration files
and, with the help of the iptables utility, configures Netfilter to match your
requirements.

Shorewall supports a wide range of router/firewall/gateway applications,
traffic shaping and almost every type of VPN.

The shorewall-lite package is designed to allow you to maintain all Shorewall
configuration information on a single system within your network.
