Private network routing issue

Comment:
We have a cisco router setup in our lab and several clients behind it which use 10.x.x.x IP addresses.
Currently if you want to search the web, or telnet into a remote box, etc FROM any system in the lab you can do so because the router is configured to route packets from inside the labs private domain out into the public domain. (very typical: nobody is breaking the barriers of routing science here!)
BUT if someone want's to telnet into one of my machines they obviously cannot because all of my systems are configured with private IP addresses.
Is there a way to route INCOMING packets to a specific machine in the lab even though said machine is configured with a private IP?

You will have to either use another public IP on the router and map it to a particular internal machine, or use port forwarding - sending all incoming telnet request on the current public IP to a particular machine on the internal LAN.
Most firewalls support these features - IP mapping and Port mapping (some call this virtual mapping).
