Two Exchange Infrastructure on the same public IP Addresson the same internal network. Let's say it's for training purpose. The present Exchange server is called EXCHSRV1 and is running on the NT domain DOMAIN1, hosting mycompany1.com e-mail addresses. A mapping on the external router maps the external public IP address to the port 25 on the Exchange server EXCHSRV1. The second Exchange server (the one which is set up for lab purpose) is called EXCHSRV2 and will run on the NT domain DOMAIN2 and host mycompany2.com e-mails addresses. What can I do to make these two Exchange infrastructures share the same external IP address, since I can't map the port 25 on the server EXCHSRV2 (the port 25 is already mapped on EXCHSRV1).

If you want it to handle Internet mail, you'll need a third party service to re-route mail from 25 to 2525 - DynDNS and others offer such 'mail reflector' services. Nicolas Macarez wrote:

Each domain can have it's own forwarding, a.com goes to server1, b.com goes to server2. Plus, you'll love the spam blocking, real time window logging of sessions, etc., that MDaemon does. Venger Many thanks to you both.
