You don't really have to if you are http://213.223232.2312.321 as your owa page from the outside. Most others would have a domain name registered or at the very least you can get a dynamic dns provider like tzo.com or dydns.org. that way you can type in www.myfakedomainname.com and it will redirect it to your network and hopefully your owa page. A few more questions though. 1. Do are you using ssl for owa? 2. What error does it give you when you try to access from the outside? 3. Have you followed Tom's Exchange deployment kit docs. It is really very easy but there are dns issues generally which people trip on. The doc explains it. Do a search on www.isaserver.org and you'll hit it.

I have only 1 Exchange 2003 server and only 1 ISA server with 2 NICs. I have web publishing rule set up using my external IP. Do I need to register a domain before this will work?
