PIX 525 Inbound connections built on wrong interface

I am using three interfaces on a PIX 525. Yesterday I moved a building with multiple subnets from the dmz interface to the inside interface. Most communication is fine. However, I cannot receive inbound connections to one address in one subnet. That address gets associated with the wrong interface only on inbound connections. When I review the configuration I can see nothing for that IP or its subnet belonging to the dmz interface. I created a route statement for the IP specifically pointing to the inside interface with the gateway of the router connected to that interface. I would like to reboot, but I have to wait for off-time hours.

Thanks for suggestions.

You will have to check the traffic as it passes through the PIX in order to determine what is the problem. You can make use of the 'capture" command for packet sniffing and network fault isolation.
