ISA - forwarding traffic form public to internal

[nicholab]

How do you set up an ISA 2004 server to use two public IP addresses. I what to be able to do multi nat due to having a second mail server and so I what to froward traffic from the public IP to my internal IP whilst keeping the old mail server working.

Could you not just create another server publishing rule?

Do you not just go through the Mail Server Publishing Wizard?

 

After choosing the internal address of the server and other things you get an option of which interface to listen on, then you can click the 'Address' button and here specify wether to use the default interface IP or a User defined IP.
