If I type http://192.168.1.1 in my browser and the LAN has no such host, should the router forward this request out to the WAN?
My home network:
DSL--> dlink router --> zyxel wireless router
I thought that a non routeable address like 192.168.x.x is supposed to stay in the LAN and *never* gets out of the router. But one router I bought (ZyXel P334W) is forwarding such address out to the WAN and is causing a problem because the "WAN" is actually my primarly wired ethernet network with a dlink router at 192.168.1.1, and the "LAN" is the zyxel wireless router which also sits at 192.168.1.1. When I plug in the WAN port, the wireless router stop responding. I have to change the wireless router's default address from 192.168.1.1 to 192.168.2.1. Now, all my wireless laptops can access (reach the login page of) both the zyxel wireless router at 192.168.2.1 and the dlink wired router at 192.168.1.1.
Is this normal?
I was expecting the laptops can access the wireless router but not the wired router.
