No.
Let me re-layout the network including IP addresses.
(INet [A.B.C.Z]) --- (BRouter [A.B.C.D]) --- ([A.B.C.E] Server(s)
[192.168.144.254] --- ([192.168.144.1-100])
Here you can see that you have the same subnet of A.B.C.x on both sides
of the bridging router. There is no good (read easy) way to have the
same subnet on multiple sides of a router short of double natting which
in and of its self is not easy to do on a singular box.
So what you do is bridge the A.B.C.x traffic to both networks and route
the other subnet(s) as needed.
Does this help?
