a firewall will do no more than a NAT router for incoming stuff
I beg to differ..............
My home router uses NAT but in addition I have it set up with Stateful Packet Inspection and blocking against all of ICMP ping flooding, IP spoofing, zero length IPs, Land Attacks, UDP Port Loopbacks, Snork Attacks, Smurf Attacks, Pings of Death, TCP Xmas Scans, TCP Null Scans, Win Nuke Attacks, TCP Syn Flooding, Ascend Kills, IMAP SYN/FIN Scans, Net Bus Scans and Back Orifice Scans. I also have it set up to block certain URLs and URL Keywords.
