I have a network where users are connected to a central site through frame circuits. They use the RTR Based FW for
Internet Traffic. Their DNS Servers are external. When users from behind the Cisco RTRB want to access the web server they have to use
the external ip address because that is what their dns resolves it to. The problem is that traffic is not coming back through the external interface when
request by the internal users. I am aware that the pix has issues with this but I thought a router would be able to handle routing back into its own interface.
Soes anybody have any experience with this? I wasn users on all 3 internal subnets to be able to access the external ip for the web server
without modifying DNS or hosts file. Help is appreciated.
