Outlook web access not accessible from the outside

Our OWA stopped working from the external IP.  Not exactly sure when it stopped, so its hard to pinpoint what caused it. Updates from microsoft were installed recently.  It works great internally. When hitting from an external IP, it does not make it to the login screen, just says page cannot be displayed.

My first thought was that the port was blocked on the firewall, but that has been tested and is open.  I have ports 80 and 443 open. My default site refreshes and sends you to the exchange dir. I can see the default site load and refresh, so I know I'm hitting the server on port 80 at least.

I've read tons of articles, but not really found any that match exactly.  There's a link out there for a problem with an exchange 2007 rollup that seem similar, but the problem ultimately was different.

This is on Microsoft windows server 2003 (sp2?) with exchange 2003 (ver 6.5.7638.1)

Just to double check, you can reach it from the inside, right? Have you run the Best Practices Analyzer?

It should be installed with the Exchange Tools, however if it isn't you can grab it here: http://www.microsoft.com/downloads/details.aspx?FamilyID=DBAB201F-4BEE-4943-AC22-E2DDBD258DF3&displaylang=en And you would want to run a health check.

running the best practices analyzer...

is there something specific I should be looking for?  Is it supposed to throw up a flag if it finds something wrong?  I have tons of nested details about my config, but nothing really ensightful.

As long as you run a "Health Check" from the "start a new scan" page, you should get back a list of details about your server configuration. A red "x" signifies a problem, a yellow triangle a warning, and a blue exclamation mark for informational stuff. If you view only the "critical" tab, you'll see items that would affect something like OWA. If there's nothing in there, then you'll probably have to move on to another solution.

wow, well apparently my backup system isn't getting the mailbox store... good to know.
other critical errors: global incoming message size not set and global outgoing message size not set.

also heapdecommitfreeblockthreshold not set.

none of those really look like they should affect owa.

you have a SonicFirewall working on HTTPS

HTTPS is required for exchange, I belive.  Can you change the port of the admin for the Firewall? Or stop remote access.  I think it's in the way..

Well, I've run out of ideas, although I can tell you that the page that I get redirected to from the link you posted is giving me an "Error reading from socket" when I connect to it with a text-based browser. :-(
