| Firewall is a set of scripts (firewall, fwup, and fwdown) that implement
an
ipchains firewall and various forms of network address and port
translation.
All you have to do is read the policy file and edit it to reflect your
topology
and filtering policy. It supports many different types of network
topology
(single host, traditional forwarding, masquerading, port forwarding, alias
port
forwarding and NAT), up to 10 untrusted interfaces each with their own
policy,
and over 50 network applications. It also supports centralised
administration
of multiple remote firewalls (meta-firewall). |
