OWA works on LAN but not on WAN

[itmt]

Hi,

Skipped 2000 in my career - went straight from 5.5 to 2003 so hoping for help.

OWA was working from WAN and LAN but now only from LAN. No firewall changes have been made and the incoming rule still points requests to mail server.

Am not sure where to start looking - all services are started - any suggestions greatly appreciated.

Thanks.

Just FYI, this is the E2K forum, you're looking for the E2K3 forum which is here:

What message do you get across the WAN when you attempt access through the firewall? Did you restart the firewall? What does the traffic look like on the firewall? does it indicate that it's being blocked there?

I'm Certifiable, not cert-ified.
It just means my answers are from experience, not a book.

Hi,

No, I do want the Exchange 2000 forum - sorry if I was unclear.

The usual "page cannot be displayed" is the error when connecting from the WAN. The firewall has a rule to forward all incoming port 80 Internet traffic to \\servername and does not show any record of blocking.

As it was working before and nothing (to my knowledge has changed on the firewall) I was wondering what the best check would be to do in Exchange/IIS? Again, it does work via the LAN though.............

Cheers,

You'd redirect to the IP of the server not \\servername. What firewall is it? That sounds like the problem.

if you use ISA and you publish another web on another machine, you have place rule for OWA on the top

Hi Zelandakh,
Thanks for that - it is a CyberGuard. The traffic is forwarded to 192.168.100.1 and the cyberguard allows you to set that resolution internally.

I am stumped. :-(

What ports are forwarded?

80 - http

ok, you ought to forward 443 as well. If you surf to root, do you get the IIS root page on the mail server?
