Description:

FireHOL is a generic firewall generator, meaning that you can design any kind
of local or routing stateful packet filtering firewalls with ease. Install
FireHOL if you want an easy way to configure stateful packet filtering
firewalls on Linux hosts and routers.

FireHOL uses an extremely simple but powerful way to define firewall rules
which it turns into complete stateful iptables firewalls.

You can run FireHOL with the 'helpme' argument, to get a configuration
file for the system run, which you can modify according to your
needs. The default configuration file will allow only client traffic
on all interfaces.
