If you have two subnets, then you need two gateways. This is
accomplished with a router that can have multiple IPs assigned to a
given interface. If your Linksys can do that, great. Just have it
answer on both 192.168.1.1 and 192.168.100.1 and call it good. If it
can't do that and you don't have a compelling reason to use a second
subnet, then keep things simple and ditch the second subnet.
