Forward Windows firewall ports

Hello.

I am going to setup me Windows Server 2008R2 server to be my main router.

But at the router i have now, i have forwarded some ports. So if you enter my IP in MSTSC you will be prompted for a password and username.

But when i setup this new server, is there then any possibilities to actually forward requests? So when you hit my public IP, then its NATs it to a Local IP?
