We have a WAN with all traffic from remote offices forced through a single gateway in the main office.
In the main office we have ports 443, 80, and 25 being forwarded to our main mail server
OWA works fine for mail boxes on this server
We also have 2 other mail servers running exchange 2003
We want to be able to access OWA for clients who have their mail on the 2nd office.
All email routes through the first office to the 2nd.
Whats the least painful way to get OWA working to the 2nd server
