So I have a primary router using the IP range 192.168.1.X and I setup a second router to use an IP range of 192.168.100.X. I setup a static IP address for the secondary router to be 192.168.1.2, and everything appears to be routing correctly. Devices in the 100.X range can surf the web just fine (which is all I want them to be able to do). HOWEVER, those devices can still see everything on 192.168.1.X range (including the router at 192.168.1.1). How can I prevent that crossover? I was looking at the firewall scripts, but don't know enough to set it up correctly.
My primary router is a WRT610N v1 running the Linksys firmware and my secondary router is an Asus running Tomato Firmware v1.28.0000.
Any help provided would be greatly appreciated.
