You need to allow both TCP and UDP for DNS to work: -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 53 -j ACCEPT -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 53 -j ACCEPT

Date: Wed, 16 Jul 2003 14:05:19 -0400 Reply-To: [EMAIL PROTECTED] named is working for me properly, if I do not have iptables turned on. As soon as I do turn them on DNS cannot reach any servers. I am puzzled. My iptables look like this.... # Firewall configuration written by lokkit # Manual customization of this file is not recommended. # Note: ifup-post will punch the current nameservers through the # firewall; such entries will *not* be listed here. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Lokkit-0-50-INPUT - [0:0] -A INPUT -j RH-Lokkit-0-50-INPUT -A FORWARD -j RH-Lokkit-0-50-INPUT -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 110 --syn -j ACCEPT -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 143 --syn -j ACCEPT -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 25 --syn -j ACCEPT -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --dport 80 --syn -j ACCEPT -A RH-Lokkit-0-50-INPUT -i lo -j ACCEPT -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 53 -j ACCEPT -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 1645 -j ACCEPT -A RH-Lokkit-0-50-INPUT -p udp -m udp --dport 1646 -j ACCEPT -A RH-Lokkit-0-50-INPUT -p udp -m udp -s 127.0.0.1 --sport 53 -d 0/0 -j ACCEPT -A RH-Lokkit-0-50-INPUT -p tcp -m tcp --syn -j REJECT -A RH-Lokkit-0-50-INPUT -p udp -m udp -j REJECT COMMIT I have been manualled editing the /etc/sysconfig/iptables file and stoping and starting iptables when I make any changes...
