On the Server:

route -p add 192.168.2.0 MASK 255.255.255.0 192.168.1.1

and

route -p add 192.168.3.0 MASK 255.255.255.0 192.168.1.1

Configure a default gateway only on the NIC connected to the DSL router.

Cisco already has the routes for the remote networks in it. If I remove
192.168.1.1 (Cisco router address) from the default gateway on the server,
the remote networks cannot connect. If I need to add those routes to
Windows, what is the command and structure to do this? Also, do I need to
write a batch file to add these routes on every bootup? Thanks.
