How do you open a port to the internet for a computer on a LAN?

My problem is this: I have a home server with the Windows Server 2003 R2 OS with 2 network cards. My internet connection goes in one of the network cards and the internet is shared to a LAN through the other card. (more: I'm using PPPoE protocol for the internet connection and the cable from the network card that is used for the LAN goes into a switch, and from there it goes to 2 separate notebooks).
I have torrent installed on a notebook and using the TCP port 20000 and I want to be able to open the port towards the internet so I can be "connectable". I tried using some windows firewall trick I've seen but that was with no luck. I also tried the Network Security panel but the result was the same:
"Error: I could not see your service on 79.xxx.xxx.xxx on port (20000)
Reason: Connection refused" (tested on http://www.canyouseeme.org/).
So, is there really any way I could open a port for one client on the LAN considering all of the information above? Thank you all in advance
