ipchains is not very much concerned with DNS, or vice versa. The
only ways these two get in each other's way is if ipchains rules
use names instead of IP addresses, or if there is no rule allowing
DNS traffic through the firewall. Please post again with a further
description of what is actually wrong, and perhaps we will be able
to point you in the right direction.
