Hello Folks, we are having trouble with DNS connectivity between client and server connected in different DMZs. Its seems that there is a problem with the subnets we are using. The inside network has the supernet and there is a static route in the PIX to reach all the hosts in the inside. Due some reason the former admin take a subnet of this supernet and assigned it to DMZ2 which is here is where the DNS server live. The DMZ has the ip subnet and here is where the DNS client live.

The problem is that despite we have investing long time in the firewall rules, the problem persist and I thing the problem is regarding the subnet due this capture I have when I try the communication between them.

%PIX-6-302015: Built inbound UDP connection 45263399 for dmz: ( to inside: (

%PIX-6-302015: Built outbound UDP connection 45263400 for dmz2: ( to inside: (

Why is the PIX building the connection to the inside instead to DMZ2?

Thanks in advanced.
