markp55 -> OWA not accessible outside LAN (29.May2007 10:23:27 PM)

I installed Exchange 2007 on my server, and OWA works inside the network (and VPNed in), but it does not work outside. I have put the server in the DMZ, and additionally, IIS permissions look good so far. Any ideas?

What error do you receive? And did you point your public IP address to the Exchange 2007 server? Is the firewall forwarding 443 traffic to the EXchange 2007 server?

BTW you should never deploy an Exchange 2007 CAS in the perimeter network.

I actually figured out the problem, it was an undocumented "feature" of the router to intercept port 443.

We are upgrading to a Cisco Pix asap. Thank you for the help!
