I have an 1841 with three FastEthernet interfaces. Two interfaces connect to separate ISP's with NAT Overload and the third interface connects to the LAN. Everyting is working fine.
I am trying to use Policy Based Routing applied to the internal interface to route all SMTP traffic to the one ISP. When I do this, SMTP traffic does route to that ISP, however there is no NAT Overload. The source address of the traffic is the inside local address of the mail server (private IP) not the Inside Global public address.
Is there some way to use PBR in this scenario yet still have NAT?
