Port forwarding in Bittorrent client in internal network with nat
I have an internal network behind a server <10.0.0.1> connected to the internet that NATs my ip <10.17.11.88> only. NAT is not allowed to any other ip addresses. When I use Transmission Bittorrent client to download torrents, I saw this in the message log and I couldn't understand it
Sat Apr 10 02:28:39 2010 Port Forwarding (UPnP) Found Internet Gateway Device "http://10.20.0.244:2869/"
Sat Apr 10 02:28:39 2010 Port Forwarding (UPnP) Local Address is "10.17.11.88"
Sat Apr 10 02:28:44 2010 Port Forwarding (UPnP) Port forwarding through "http://10.20.0.244:2869/", service "". (local address: 10.17.11.88:51413)

Sat Apr 10 02:28:44 2010 Port Forwarding State changed from "Not forwarded" to "Forwarded"
The thing is that this 10.20.0.244 is not my machine and doesn't have access to the internet at all. What is happening here? Can anyone help me?

If your machine is not the gateway then the ip listed must be the gateway, or the front end server.
Do you know what a gateway is ?
Your machine connects to another machine that connects to a GATEWAY.
The gateway is the router.
UpnP will create a virtual device to cope with connections.
If you don't like it, turn UPnP off and deal with the hassle yourself. Universal Plug And Play
The whole point of UPnP is that you shouldn't even see this stuff going on. It's good that you spotted it, but don't freak out because it's not traceable. Too many people question things that are done for their own good.
If you're worried, try accessing that ip from outside your network by "normal" means.
