Its not quite that easy nofx 192.168.1.* and 192.168.2.* are still on the same subnet or "network". To put them on separate subnets, you would have to assign one a 255.255.0.0 mask and the other a 255.255.128.0 mask. your ip range would be 192.168.1-127.* on the first subnet and all ips on the second subnet would have to be 192.168.128-255.*. However in doing all this, you arent setting up a traditional lan. You wont be able to see the computers on the opposite network you are on. I think what ZD was trying to do is allow one router to act as a dummy switch and just performing layer2 functions, while the other acts on layer3, and does things like port fowarding, dhcp, firewall...ect. It makes it easier when you have multiple routers and want one to act as a switch. Thanks for the read. I had been wondering about that, and was having troubles doing this.
