We just installed a WatchGuard Firebox firewall. For incoming, we have SMTP-Proxy and SMTP both on port 25 allowed, but we are not able to receive emails. Email shoud come to Exchange Server 2003 SP1.
A 1-to-1 NAT for the exchange server is in the config.

Can you update of you are getting any errors/messages in traffic monitor; please mask two octets of all public IP addresses.

If you configure filteredSMTP instead of SMTP proxy service does the email come in fine.

Please update,

Thank you.

Is the external IP address you have 1:1 NATed to your exchange server dedicated just to the exchange server?  If so you are most likely missing a policy From: Any-External To: your External IP address.  You can use Any protocols or http: https: POP and SMTP if you are using these protocols for your Exchange server.

If you are not dedicating the external IP address just for Exchange I would remove the 1:1 NAT and add a separate policy for SMTP, POP, http and/or https From: Any To: NAT external IP address to internal IP of your Exchange box (for each of the protocols you are using).

Hope this helps.

This is a non-issue at this point.
WatchGuard will not be a solution provider for us.
Thanks to all who responded.
If the tech support for them was as responsive, they may have not lost us as a customer.
Is there something I need to do to close this trouble ticket?
