Linux has it's own firewall (netfilter/iptables).  It works.  Now if
you're looking for help in configuring the firewall there are several
scripts like shorewall, fwbuilder, bastille (which does more than
firewall), firestarter, or even good old vi.

(note that many "hardware" firewalls run linux and iptables)
