I do not know lot about networking but learning slowly so this might be a stupid question but here is my dilemma.
I have a router 1, set to LAN IP 192.168.1.1 and it has DHCP for LAN to 192.168.1.xx
I have another router that is behind Router 1 which's Internet IP is 192.168.1.31, Gateway is 192.168.1.1 to get to the internet. 2nd router also have devices so the LAN IP is 10.0.0.xx
I want the 2nd router and its devices to isolate from having access to 192.168.1.xx., how can I do that?
With this setup this is what i observe, If my ip is 10.0.0.10 then i have access to 10.0.0.x and ALSO 192.168.1.x. But if i am 192.168.1.15 then i only have access to 192.168.1.x and not to 10.0.0.x which is ok and i understand that router 2's firewall is blocking it.
However, my main concern is how to block the traffic of router 2 from seeing any device of router 1 (192.168.1.x)
Attached is the screen capture of the setup
Possible solution is to setup setup some forward rule? or restrict Router to different subnet and how?
Any help will be appreciated, Thank you
