Reach lan devices from wan router

Installing and Using OpenWrt
1

I am using openwrt as secondary router connected to main router (wan) wirelessly.
I can ping devices connected to main router from openwrt but not vice versa.
Is there any way to reach devices connected to openwrt through the main router

different subnets ?

firewall in-between ?

Yes, both main router and openwrt router having different subnets.
Main router - 192.168.43.1/24
Openwrt - 192.168.43.2/24

typo, I assume.

Any special reason for keeping the two units on diff networks ?

On the main router, configure a route:

  • destination: 192.168.42.0/24
  • next hop: 192.168.43.2

Also allow forwarding from wan to lan zone and disable masquerade on wan zone.

Main router(tenda n301) just allows basic features.
No routing option is there

Can you provide me a better method.
I am using openwrt as a range extender but it has some features like dns server, vpn so I am using it with different subnets from main router

Port-forwarding from main router to OpenWRT's WAN address in the same subnet?
Corresponding port-forwarding on OpenWRT to devices behind it?
