 Subject:  DNS Issues on Opt 1 network
 Date:  Mon, 7 Aug 2006 14:55:40 -0700
My lan network is 192.168.2.0 with lan gateway of 192.168.2.2.
The 2000 server is 192.168.2.1 and is providing DNS resolution.
 
I have setup my OPT1 with a network of 192.168.1.0 and the OPT1 gateway is 192.168.1.1
The 2000 server for that network is providing DNS resolution.
 
I have setup a rule in the OPT1 interface allowing traffic from the OPT1 interface to go out without
restrictions similar to the LAN rule.
 
Everything is great but non of the systems trying to go out to the internet from the OPT1 network
cannot resolve internet addresses.  I am able to RDP into systems meaning I am able to remote
control systems on the internet.  But no DNS resolution.  The firewall log says there is
communication on UDP 53.
 
If I change the DNS of the local PC from pointing to the server 192.168.1.2 to for example 4.2.2.2
then I am able to get out onto the internet.
 
Very fustrating.
 
Thanks,
 
Mark
