Assuming that your router is at a.b.c.e then add the following to
the top of your startup script to eliminate the route created
by the gateway entry in the boot parameters.

routeDelete ( "a.b.c.0", "a.b.c.e" );
routeAdd ( "a.b.0.0", "a.b.c.e" );

This will allow communication with any host on network a.b.x.x. 
You can be more specific about what you will allow by using
several routeAdd commands specifying only the subnets that
you will communicate with. For example this will allow communication 
only with subnet a.b.10.x a.b.11.x.

routeAdd ( "a.b.10.0", "a.b.c.e" );
routeAdd ( "a.b.11.0", "a.b.c.e" );

Or if you don't want to allow any off-subnet communication then
perform the routeDelete() and don't bother with the routeAdd
above.
