Hey all, was hoping maybe someone could help Me.  I have turned my firewall
to a deny all unless matched previosuly and it works great. lots of weird
packets and I dunno what they are but are getting blocked, ha.  Anyways, I
have setup 2 rules to add in my dns server.. here they are

00073    264    16586 allow udp from <network ip range/16> to <nsaddress> 53
00074    262    75464 allow udp from <nsaddress> 53 to <network ip range/16>

as u see the rules are running fine.  I can surf and do whatever I want on
the 5 computers behind the gateway/firewall.  Everything resolves fine and I
have checked to make sure I have the proper dns servers on the other
machines behind the gateway.  Where my problem comes in is here, The bsd
machine with the gateway and connection is not resolving, on anything.  But
still operating fine for some reason.  Anybody know how I can get the
gateway to resolv properly.  Thanks

Matt Thomas
