a Router behind a computer

[Orincarnia]

ok my situation is kinda weird.

the cable line goes into my moms office, into the modem, and then into the router, an ethernet cable goes through the wall to connection 1 in my desktop.
i have 3 NICs in my desktop, and i want to use them. i have connection 2 going to a storage computer. and connection 3 goes to a router that is sitting in my room.

i have successfully gotten internet on a computer that was directly linked with a crossover cable into the computer from connection 3. but now i want to throw that router in there so i can have 4 extra ports. but nothing works.

(its a linksys BEFSR41 kinda old i know)

how can i make a connection that has internet when directly connected, have internet when its going through the router? (btw i can't even type 192.168.1.1 and get the router on the one computer connected to my router)

anyone know what i'm trying to do?

I'm not sure what you are doing.

But I suggest you start over. Connect your router to the main router. Then connect your PCs to your router.

what are the advantages of having more than one NIC in a computer?

really the only reason i'm going from computer to router, is because if a router can serve up internet to a computer, why can't a computer serve up internet to a router?

what i want to do is have my desktop connected to a router, have that control internet flow to a laptop (connected to the router) and then have extra ethernet ports for friends who bring their computers and don't have wifi in their computers.

Most folks add ethernet ports via a hub or a switch. It's a lot easier than multi-homing a computer.
