Binary package “shorewall” in ubuntu lucid
Shoreline Firewall, netfilter configurator
Shorewall allows firewall/gateway requirements to be described 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 these requirements.
Shorewall supports a wide range of router/
traffic shaping and almost every type of VPN.
