I have a pair of failover Pix 515e running software (8.02) and I have 6 interfaces. Outside, inside, inside2, DMZ1, DMZ2, failover.
DMZ2 contains our external DNS server that services DNS requests for our domain and several client's domains that we host. We recently moved a client's dedicated server to DMZ2 and now DNS doesn't work between that server and our DNS server because they are always looking to route to the external IP but they are on the same switch and interface of the Pix.
What I need to know is how can I either route the traffic so it doesn't try to go out and back in or some solution for servicing DNS requests to outside and locally differently. Any help is greatly appreciated.
