On the market right now there are, that I know of atleast, 3 free good firewalls. Theese are , Iptables ( i leave ipchains behind because iptables has proven itself to be relativly stable since it was released over a year ago) Packet Filter and IPfilter. If i got this i right most people see IPfilter as the most mature solution. What drawbacks does IPtables and Packet filter have compared to IPfilter? All opinions about these firewalls are welcomed =)
