Webserver and Exchange 2000 server

Hi,

I have a dsl connection with one static ip. I also linksys dsl router on my 2000 network. Currently, I have successfully set up Active Directory and Exchange 2000 sever and everything works fine. My question is, can I setup a webserver and a ftp server on the same server as the exchange server with one ip. I was unsure because the exchange sever uses the default web for outlook web clients and since the router forwards all http requests to the one server i wasn’t sure if it’s even possible. If not what can I do in my situation to add a webserver and a ftp server to my network?
