Exchange 2003 OWA second IP address issues -- Sonicwall NAT --
Posted on 2005-03-29
My issue involves OWA for Exchange 2003
I just upgraded our domain from NT to 2003 and went from Exchange 5.5 to 2003. On Exchange 5.5 we had OWA setup with a different IP than the actual Exchange so that I can use my Sonicwall Firewall to NAT my live IP's for Exchange and OWA to the same physical machine. The Sonicwall won't let me NAT 2 Live IP's to the same internal IP.
I added a second IP to the adapter, and then changed the Default Web Site in IIS to use that second IP instead of "all unassigned".
I changed our Sonicwall to NAT the OWA live IP to the IP that I put in IIS.
When I try it internally I can use that new IP/exchange and access OWA, but when I leave the Lan and try to come in externally it does not work. The page does not respond.
Any ideas would be helpful.
