OWA just quit working from the Internet, "Page Cannot Be Displayed"

It is a SBS 2003 server with SP2 and SP2 on Exchange.  OWA had been working for some time but now all you see when attempting to log in from outside the LAN is "Page Cannot Be Displayed".  The firewall is a TZ180. Its config has an access rule allowing HTTP and HTTPS (443) to the server and the logs show no record of blocking any access attempt to the server.  I can disable the HTTP rule and see that the TZ180 is now blocking the attempt so I believe the problem is limited to Exchange / IIS.  No changes that I know of have been made to either. Nothing in the Application or System event logs.  VPN connection to the TZ180 stil work.  
Suggestions?.

Sounds like its an issue with the Sonicwall.  Do you have a spare firewall you can use for testing?

If it was a problem with IIS or Exchange it would either not work on the LAN or at least generate a specific error when being accessed externally.

Turns out Waye Williams was correct.  A test I did not do was to enable everything from the WAN to the LAN in the TZ180.  That allowed OWA to work.  I deleted and recreated the access rule, turned the everything from WAN to LAN ruke back on and all is well.
Thanks Wayne.
