A friend of mine has 2 macs in his office - and wanted to purchase a router so that they could both be on the Internet and doing some file sharing. ( I guess currently only one computer is on the Net - the other is just a non Internet Business Computer right now.) I suggested that his company might already be on a Bigger master router system ( there are about 30 employees) - and he thought that most likely there was some previous system set up and that he was already receiving 1 Ethernet cable that was probably on that system already - he wasn't sure - but that is my guess. However, he still wants to purchase a router to set up these computers in his room. So I am asking - is it possible to purchase a router and set up on top of another ( bigger) router. Let's assume that the large office gets 1 T1 line coming and - and goes to a master router - and one Ethernet cable goes into his office. Can I then attach his private router to the end of that cable and set up a " sub system " for his 2 computers? thanks to advance for your help - RevDave -- Thanks - RevDave CoolCat at hostalive.com [db-lists]
