Routing Traffic Over PTMP

Hi,
What I am trying to achieve is, access the devices on network 192.168.10.0/24 from network 192.168.20.0/24. I got this working fine with hardwire between A-B & A-C. I can’t however get it to work when I install the wireless links between the two locations. Then for some reason this no longer works. Any ideas how I could get this to work?
I have attached a brief network diagram as to how my network looks.
I am clearly missing something but I can’t quite figure this out.
Thanks

try static routing:

on B Hap ac2:

/ip route
add distance=1 dst-address=192.168.20.0/24 gateway=192.168.1.252

on C Hap ac2:

/ip route
add distance=1 dst-address=192.168.10.0/24 gateway=192.168.1.253

check your firewall rules

If everything works for you when connected by wire, then routes, etc. configured correctly.

Check the operation of the radio part.

  1. “Client isolation” is set to OFF on LTU Rocket?
  2. Ping from MIkrotik “C” to LTU Rocket (from 192.168.1.252 to 192.168.1.254, as I understand) successfully?

Massive thanks to BrateloSlava, the Client isolation was set to ON.
I was looking in the wrong place for the problem when I knew the traffic wasn’t flowing through the rocket.

Thanks so much. Glad this is now working flawlessly. Thanks for the assistance.
