Squid is not a firewall. It is an HTTP proxy. You could, at a pinch, call
it an "application layer filter" because it can control access to HTTP
resources for the network based on application data in HTTP packets.
Linux has come pre-installed with firewalls since the 2.0 series. 2.0.x
had ipfwadm, 2.2.x had ipchains, and 2.4.x has iptables. The 2.4.x series
iptables supports stateful inspection, full nat connection tracking, and
many other very useful things like packet mangling for advanced routing.
Try finding that for free anywhere else :)
