True true true :) I have never heard a completely satisfying answer for this, but my empirical experience, you cannot access a server by "bouncing off" the external IP address and back in. I've tried with PIX, CP4.x, and Watchguard, all with the same results. The answer is usually to set up internal DNS for the machines you need to access, and educate users accordingly. If anyone has an explanation (or, better yet, a solution) to this conundrum, please post. A thought: if you disable anti-spoofing, does it work? Dan Hitchcock Network [email protected] Xylo, Inc.

It send and recieves SMTP mail fine. POP3 clients from the outside work fine. When users from the inside use the "valid" IP address for the server they cannot connect with their POP clients to the Exchange server. Martin D.
