Hi Carson, You need to use Server Publishing Rules to publish SMTP servers. So, for each instance, you need a separate IP address. Unlike the Web Publishing Rules, you can publish multiple servers with a single IP address.

Is that possible for exchange 2000 to have single internal IP and ISA server has single external IP? Since the server publish rule don't give you option to specify port. It only redirect everything to its external NIC port 25 to internal exchange server 25 port. So, I cannot find way to work it out. Any input? Thanks.
