CopperJet 810 - newbie help please!

Hi

can anyone help me set up this bridge/router to connect to ADSL with a
single PC (not networked but using a NIC card to connect to the router)? I
want to connect an Xbox to the router too so that I don't have to turn the
computer on each time I want to use xbox-live

Have a single static IP address and have tried loads of ways to configure
the router - no luck though.

Anyone got any clues?
