Hi Jerry, according your rules you have opened all incoming traffic to interface eth0 and eth1. I think that is the issue. Try to remove or modify them -- -A RH-Firewall-1-INPUT -i eth0 -j ACCEPT -A RH-Firewall-1-INPUT -i eth1 -j ACCEPT Check how your other rules are working - take a look in the output of "iptables -nL -v --line" command (see packet count row)..
