Outlook Web Access through firewall

[mufka]

I have a Exchange 5.5 SP3 server behind a Raptor 6.5 NT firewall. The firewall has 3 NICs. One for the external, one for the lan and one for a DMZ. I want to put an OWA server in the DMZ so users can hit it from the outside to access web based email. The OWA server needs to be a BDC (to have one user list) so I installed it on the LAN. I changed the IP address and moved it outside into the DMZ. I can't seem to get the OWA to work through the firewall though. I can get it to install, but when I try to open it, it just keeps searching forever. I am using LMHOSTS to locate the Exchange server and the PDC (exchange is on another BDC). Even if I open the DMZ completely to the LAN, it won't work. Once I get it working, I'll want to tighten down the security. In testing I think I tightened it down as much as I could for the Domain traffic (cifs, nbdgram, port 135 and netbios_139_tcp).

Is there a right way to do this?

You need to point OWA at the Raptor. Then you need to use something akin to a virtual directory to forward the request to the Exchange server.

The OWA help files have something on this as I recall, but it may have been the MS notes on Exchange. At my age, I can't remember...
