I am trying to get the following scenerio to work:
I have one IP address that the DSL carrier has povied me for the OUTSIDE interface. I need to Have all internal systems go out through this interface ( I am currently using PAT ), I also need to forward port 25 traffic that goes to the OUTSIDE interface to forward to an internal Exchange Server.
The problem that I am having is that when I enable the port 25 translation on the outside interface, I loose the ability to get to the internet from internally.
Can you have the outside interface translate this way, or do I have to get an additional IP from the carrier?
