I did exactly what you said and that worked. as far as the router, you are
also probably right, although i will look at the manual some more. So i have
to look for an option called loopback?

It is actaully a combo dsl modem and router in one. That is what verizon
supplied me with. I would have liked to use a linksys router, but there is
no option to shut off the router and just use the modem. Its is a Westell
327. Thanks
