I am trying to extend a router provided by an ISP. The setup is a bit cryptic as its in French. I believe the section I need to change is the Router tab which asks for Destination, Subnet and Bridge IP addresses. Draytek's instructions for WDS apply to my Draytel 2920n but am I flogging a dead horse trying to connect to anything non-Draytek?

A bit of background - I am staying for a few months in a French gite where I have access to wifi internet but need to connect my VOIP phone for which I must use an RJ45 cable. The modem/router is in the next door landlords place.
