routing

I've got 2 Netgear N300 (WNR2000v3) routers.

Here's my setup:

Modem > Router 1 > Private Users/Router 2 > Public Wireless Users on "Guest" Network.

I want to prevent users who are connected to Router 2's "Guest" network from accessing anything that is connected to Router 1. There is an option when setting up the "Guest" network called "Allow guest to access My Local Network" which I thought if unchecked would do this very thing; however, I can still access files and such of computers connected to Router 1.

Router 1 assigns 192.0.0.x IP addresses, Router 2 assigns 10.0.0.x IP addresses, how can they even see each other? Do I need to change the subnet or something else?
