Help setting up OWA behind a firewall

[sprintst955]

I have Exchange 2003 setup in a W2K mixed-mode environment. I am able to hit OWA locally on the LAN, but I can not hit it from the web. I have setup NAT to direct http requests to the exchange server. I have setup the ACL to allow traffic on port 80 to pass. Is there anything I could be missing?

Unless this is purely a hobby type of environment with nothing at stake, the only port you should have open is 443 and you should be using SSL.

on the router/firewall you need to forward port 80 (or 443 for SSL) to your LAN-IP of the Exchange server. Basically, that should do it.
A simple NAT is not enough.
For better security, use port 443, as suggested above, or even a custom one, to avoid obvious standard port scans.

Also, read through other post in these forums, this issue has come up several times already, you surely will find your answers there too.

What is the command for port forwarding on a Cisco 1601? This is a test environment and I will be using SSL when I get the kinks worked out. Thanks to everyone for your help.

that is not a question for the Exchange forum, please ask that again in the Cisco forum.
