Accessing client computers behind a firewall from the internet

I have a small network using windows 2003 server and NAT to provide internet access to client computers on my network.  Some of the users want to be able to access remote desktop, file sharing, or FTP from home over the interet.  I know I can map ports to local IPs, but I was wondering if there was a way to create a discrete name for each of the clients that would work on all ports, something like client1.router's.internet.ip  Other suggestions for something like this also greatly appreciated.

The obvious solutions are to statically NAT all the clients (ugh!) or dump NAT entirely.  Somehow I doubt that either is practical.

So the next best would be to implement a VPN, allowing authorized users to connect in from remote locations and get access to private resources on the LAN.

What type of firwall are your running?  If you are running a Cisco, you could build access lists (of all the users internet ip addresses) that give total access (ip, udp, tcp, icmp) to a particular list.

I am using the Routing and Remote Access feature of Windows 2k3 for my router.  Any info on how to statically NAT address would be very helpful.
