I recently setup Exchange 2003 SP2 and it was working fine, including POP3, OWA and other services. I had to install a new firewall / router and was required to change the outside ip address as well (gotta love comcast). After I setup the new router I created the standard port forwardes for 25, 110, 80, 443 and others that we need. I have port 80 & 443 (although we are not using a ssl yet) to forward to our exchange server.
after i put in the new router with the new wan ip address, i am unable to access owa from the outside. browser says it can't find the page htt://xxx.xxx.xxx.xxx/exchange. it worked fine before installing the new router.
are there any settings in IIS or Exch 2003 that I need to change since I installed the new router.
I've checked the forwarding rules and they seem to working.
