i'm in NY but i want to my router to have a UK IP,help!?

[strawdog]

i have a netgear router and a decent broadband connection here in NewYork,i have a UK xboxlive account and i really want to set up the proxy settings on the router so my xbox thinks its in the uk (for sky player etc)
anyone know of a simple website that will lead me by the hand through setting up a UK proxy configuration on the router.
i have managed to get my explorer browser to work with a uk proxy but i am unsure if i can do the same with the router/xbox360

thanks
