Isolating wireless from wired with two routers

[Nedved11]

I've got myself two wireless routers, a Linksys WRT54g and a Netgear WGr614. I know you can use the custom firmware on the linksys to set up separate VLANs for this purpose but don't really want to mess about with that.

I have currently got Router 1 (Wireless disabled) connected to the cable modem. I have configured the 2nd router to use a different subnet and used the DNS servers from my ISP and 3rd DNS using router 1's IP. Connected Router 2's WAN port to a LAN port on Router 1. Now I can pick-up up wireless fine and get internet connection however I can still see IP's from the router 1's subnet.

I'm trying to figure out what the best way would be to isolate the two?

Any input most appreciated.

Cheers

I think you've got it back to front.

Put the wireless onto router 1 in your setup and I think it'll work as you want.

If you cascade routers like...

Modem
|
Router 1
|
Router 2

then there'll be a valid route from router 2 to router 1. If there wasn't then you wouldn't have a valid route to the modem.

However there won't be a valid route from router 1 to router 2 unless you deliberately configure it.

Cheers for that, that does make sense. Will give it a try.
