Im setting up my network at home for adsl and I need to check that everything is correct. I have two pc's and a switch and I'm looking to buy a router/modem. There issa cheapish one, billion 5102S, but it only has one ethernet port. So I figured that I could just plug the 5102S and the two PC's into the switch and use the 5102S as a default_gateway on both PC's. Will this work?
