How can I isolate OpenWRT router from the other routers?

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi everyone!

I have this network schematic:

192.168.1.1 - ISP router

192.168.10.1 - Cuby router connected via WAN to the ISP router

192.168.12.1 - OpenWRT router connected via WAN port to Cuby router

I want to have WAN connection on 192.168.12.1 but I want to isolate 192.168.12.1 LAN from the other router. My goal is to use my IP cameras with the OpenWRT router and so isolate them from the rest of the network. I know I can do firewall rules, but I've tried on OpenWRT firewall settings without success.

Can please anyone help me in doing that?

Thanks in advance for the reply!

Create firewall rule(s) stopping access to the .12.1 and 10.1 subnets on the Openwrt router.

as you can see you can add a 2nd subnet to the destination address field.

Thanks a lot! Now I can't access to 10.1 and 1.1 from 12.1

Is there any way to avoid the ping of 193.168.10.1 and 192.168.1.1 from 192.168.12.1?

add ICMP to the protocol list.
