Make sure that: 1. the internal server is a secureNAT client. 2. Your ISA TCP/IP setup is correct.

I have tried both manually and with the wizard. I am using telnet to verify the connection. When I connect (via telnet on port 25) to the mail server I get the welcome message. But when I telnet from outside to the ISA server on 25 it just sits there with no welcome message etc. It doesn't seem to be piping the request through correctly.
