This is application dependant in a sense. You can change the external port allocation to resolve the the correct internal port on each machine.
Say for example were using rdp which uses (protocol/port) tcp/3389, the application (RDP client) actually allows you to change the external port to connect to if you specify it after the ip. So for instance say we want to have rdp access to all 3 machines from the outside world. We can setup port forwarding to each computer
(Computer) (internal IPort) (external IP/port)
Comp A 192.168.0.5:3389 203.x.y.z:3389
Comp B 192.168.0.10:3389 203.x.y.z:3390
Comp C 192.168.0.15:3389 203.x.y.z:3391
This is the purpose of a router, to create routing tables.
You'll obviously have to remember which ports are allocated to which device.
This is certainly application dependant. Find out if your application or service supports the port change, ftp clients, rdp, tftp, ssh all do.. Most 'Good' services do, as those who have constructed it have considered a NAT environment.
NAT = Network Address Translation
Most things if not at the application layer, even services in windows are tweakable via the registry. I wouldnt suggest you do this if you dont have the relavent experience. You'll potentially render your workstation inoperable if you get it wrong.
Hope this helps.

Ok I feel you. But another problem emerges - I got only 15 fields to fill up in the configuration. Is it possible to extend it someway?

Hi there all,
I hope one of you can help me....
I have bought a new WRT160NL and I wanted to forward a port so I could use the program Gigatribe.
For some reason my router doesn't remember the data I fill inn?
I fill in the fields with; name, port in, port out, both, enable and when press Save Settings, I get the pop-up that the settings are saved, but than a blank screen appears and nothing of the data i filled in is vissible???
Also the port I wanted to forward is still closed.
Am I do something wrong here??

Actually you're pretty wrong. Just because Linksys doesn't offer this doesn't mean it's not possible. The CORRECT functionality, which is (at least) not implemented on WRT320N, is that if you have the same port/port range for an application, you can enable it for multiple computers, and what the router would do is have a list of enabled computers to forward the traffic to. In other words it forwards it to each machine. Sending packets to a destination that isn't listening is a pretty insignificant price to pay to be able to:
- VPN from more than just your office compuer
- Have your kids with different computers be able to host games online
- Bittorrent on multiple computers
What's even more pathetic is that the Actiontec routers distributed with verizon fios these days has this feature.
(Mod Note: Edited for guideline compliance.)
