I have a mail server that is in the DMZ which is behind the Cisco 2621 router. I cannot get it to ping past the internal interface. There is a ip nat statement:
ip nat inside source list 10 interface Dialer1 overload
But this is not helping, the Dialer1 interface has "ip nat outside" in it's configuration. What else do I need to get this server to access the outside?
I've included the config file for the router.
