FW-1 Uses stateful inspection, which is way more secure then the packet
filtering techniques of ipchains and others. It's not right to compare
between the two, because the question is cost-effectiveness. FW-1 is must
more full-featured/robust/strong, etc but costs 5 digits to buy.

Download a security scanner (www.nessus.org is an excelent security scanner)
and run it against your box. Remember, though, that testing yourself is
always problematic, especially if you're not familiar with security. Join
bugtraq and debian-security, search for firewall setup guidelines and take a
look at the latest ipchains exploit (which might change your mind about
ipchains vs. FW-1):
