I want to run a web application on a Win2K3 server sitting behind the corporate firewall (which is ISA). I need to do this because the server needs to access an internal EDMS using just DLL calls, not web services so it's tricky to put the server in the DMZ. We already have ISA which routes VPN traffic to our domain controller and OWA which routes traffic to the Exchange Server, both of which are behind the corporate firewall. If I have a specific URL for the internal server, is it possible to route traffic only that URL on port 80 (we are not planning to use SSL) to the internal web server without compromising security for the corporate LAN?

Hi, I think you will get your answer much quicker, if you will post into the appropriate forum for ISA server: http://social.technet.microsoft.com/Forums/en-US/category/forefrontedgesecurity
