Once again:
Please show the set-up of different hosts (machines/computers) in your
proposed system, and mark which of them run Windows and which Linux.
In principle, there must be one computer connected to both subnets
and it has to be set up so that the packets are forwarded between
the subnets. This implies enabling IP forwarding and a suitable
routing table. It may be necessary to set up routes in the other
computers, too.
Subnet routing does not transfer all Ethernet traffic, only IP traffic.
If you need transferring Ethernet frames other than IP frames, you
need to set up bridging in the computer connected to both nets.
For Linux, there is a HOWTO document about bridging.
Sorry for not giving more details, cannot do it without sufficient
details of your set-up.
