routing two private subnets?

I apologize if this question gets a little convoluted, but here goes. I
recently moved my servers to someone else, so I no longer needed a
dedicated internet connection. I now have a residential class DSL line.
  The modem provided (speedstream 5100) can be optioned to operate with
external or internal pppoe. The modem is “hardwired” to 192.168.0.1. I
have everything currently configured to use RP pppoe, but I would like
to use the modem’s pppoe (and NAT) and use the connected machine as my
barrier/router/firewall. Is it possible to set up the interfaces on the
router to addresses in the same subnet (i.e. eth0 & eth1 both on
192.168.0.0)? Alternately (probably simpler), I can configure two
subnets (192.168.0.0 & 192.168.1.0). Either way can I use iptables to
NAT or masq to allow my other machines (all on private ip’s) internet
access?

Thanks
Bill
