I have an ASA 5505, and a Symantec 5000 series. On the Syamntec box, I can redirect a port as well as dynamically assign an IP address from a pool. I use this with SMTP to redirect two inbound IPs to my single internal email server. The email server knows which way to go back by looking at the IP address assigned from the pool (i.e. 10.200.1.x = IP1 and 10.200.2.x = IP2). How do you do this on an ASA5505? I'm sure this is simple, but I'm in a small shop, and I'm spreading my time across many areas right now. Thanks!!!
I have this problem too.
