What does your resolv.conf say?  Is it pointing to itself?  If so, does
your ipchains implementation allow itself to use the loopback
interface?  Another thing to be aware of is that DNS lookups are not:

	domain ->  any


but rather 


	"ports greater 1024" -> domain


When I did ipchains, the best reference I found was Robert Ziegler's web
site and book.  Respectively www.linux-firewall-tools.com (follow the link
to  the script generator) and "Linux Firewalls" New Riders publishing.
