I've been scouring the search engines trying to find a way to set up multiple web servers behind a single-IP NAT router. Basically I want to configure my setup so that http://server1.mydomain.com (public) translates to http://192.168.1.2 (private) and http://server2.mydomain.com translates to http://192.168.1.3/exchange/. The only suggestion I've come across so far is setting up the router for port forwarding, but I want to keep everything on the default Port 80. I would also like to my local LAN users to be able to access these servers not via their internal addresses but by their public URLs.
I don't think it's really relevant, but just in case, Server2 (192.168.1.2) is an Exchange Server running Outlook Web Access. Perhaps someone can point me to an article or lend some advice?
