Again it depends, how you setup your default policies. In case you are
using recommended "default DROP" then you have to tell iptables to
allow "udp 53" towards your ISP.
iptables -A FORWARD -p udp --dport 53 -j ACCEPT
If you are running a small LAN then running a cache only dns on your
gateway would be beneficial, (that it will cache the lookups)
dnsmasq is excellent cache only dns server and i'm sure you would get
is running within 10 minutes.
you can also use bind in cache only mode.
