I think the diagram got a little garbled in my mail reader, but if the
192.168.100.0 network is on the other network interface of 'Router'
(192.168.1.2) then the following applies.

The default route in a machine is the route that is used after all other
routes have been checked. For machines in the 192.168.1.0 network to have
connectivity to the 192.168.100.0 network, add a network route to
192.168.100.0 with the next hop gateway as 192.168.1.2.  For machines on
the 192.168.100.0 network, because (if I understand your network's
topology correctly) connectivity to all other networks is through
'Router', a default route with the next hop gateway being the
192.168.100.x network interface on 'Router' will suffice for them.

Hope this helps...
