Your echolife must be in bridge mode. So it is no longer acting as a router. So no need to worry about this part

What I would like you to do is post 2 screen shots for me.
1. Open a command window and put in ipconfig, get me a screen shot showing your computers local IP
2. Go to the port forwarding page in the bt home hub and get me a screen. This will let me see if your port forwarding rules are done right.
Lets go from there
