I think you dont want that ! (If I'm wrong, I peg your pardon - then you
should google about dhcp relays or bridging)


each networkcard should represent one subnet. Otherwise your route-PC will
not know on which networkcard it should send a certain network-packet.

Your dhcp-server on the cable-modem only gives ip's for one subnet.

So what you want is maybe something like this:

A) the cable-modem and all your PC's are connected via a switch. Then all
PC's will get their adress inside one subnet from the cable-modem

B) each PC is in its own subnet and the route-PC masquerades the
connections. Then you could setup a dhcp-server on the route-PC or just
assign static adresses.
