iptables firewall and DNS?
 
Hola
Wasn't sure where to post this but here goes.
I just put in an iptables firewall using my server (dual-NICed) as the gateway.
Everything thing seems to work, except local DNS. I am running DNS on the same machine and it no longer works. If I send DNS requests outside onto the Net everything works fine. Is iptables and DNS on the same box a bad idea?
Thanks much.
:Pengy:

I have iptables and dns in the same box with no problem.

Have you accidentally blocked udp traffic from your LAN (especially to port 53)?

Hey
I think that may be it. I forgot to open UDP:53. I'll double check. Thanks much.
