Hello,

	I want to do some traffic shapping with a PC in the same IP subnet that
the "shaped" PC's.
	Graphically:

              ________              __________
             |        |            |          |
Internet-eth0| NAT/GW |eth1----eth0|  TC BOX  |eth1 --- SUBNET PC's...
             |________|            |__________|


NAT GW (Nat Gateway) Specs:
eth0 IP: AAA.BBB.CCC.DDD Public Address
eth1 IP: 192.168.0.1/24

TC BOX (Traffic Shaper):
eth0 IP: 192.168.0.2/24
eth1 IP: 192.168.0.3/24

SUBNET PCs:
Netblock: 192.168.0.10/24 - 192.168.0.254/24
Default GW IP: 192.168.0.1

Is possible to make that my TC BOX acts transparently for the subnet PCs
without redefine the default GW to 192.168.0.3 (the TC inner interface).

The intention is not add another Hop to the network, and lower the CPU
usage of the TC BOX (i don't want to do NAT on it).


Thanks.
