Do I have to have multiple external IP address to publish multiple exchange server from Internal network ? In other word, is server publishing requires one-to-one mapping between external IP address and internal IP address ?

Thanks.

Hi Yanping,

yes, server publishing requires one-to-one mapping between external IP address and internal IP address for the same service (port number). In other words, if you have two internal services on port 25 (SMTP) then you need two external IP's, one for each internal service. Moreover the service port number must be the same externally and internally.

However, if it is acceptable you can run one internal service on an alternate port number and server publish it on the same external IP on the alternate port number.

HTH,
Stefaan
