I have two networks at home. One uses a Verizon mifi wireless on 192.168.1.1. The other uses a dlink router on 192.168.0.1. I have one laptop with two nics, one wireless and one not. The wireless nic connects to the mifi. The Ethernet nic connects to the dlink router. It's ip is 192.168.0.2. I also have a laptop with only one nic connected to the dlink on 192.168.0.3. I want to connect laptop 2 to the Internet. Can I do that by adding an entry to the routing table so that destination 0.0.0.0 routes to 192.168.0.2?

If I do that, will laptop 1 "know" that it should route traffic from 192.168.0.3 to 192.168.1.1?

Thanks for any assistance.
