Thank you all three,
I set up a demo to see where the issue is and followed mbo2o ipcalc to stays within appropriate IP.
1043ND being used
So…
Gateway 192.168.100.1/24-255.255.255.0 <----> RouterA 10.64.5.99/24-255.255.255.0 <----> Router B 10.65.6.30/27-255.255.255.254

What should I do to Reach Router A and its LAN devices (Printers, File Servers etc) from devices on Router B
With this direction of communication there should be no issue at all!
crazy issue.
The other way round I would have understand but no access from B to A is weird!
Even weird is that communication can go pass Router A to reach Gateway - no firewall and no blocking in between
I will stop fighting the issue get some other routers or return to basic firmware and see. If good will set up linux box to do services which are actually being done on the OpenWRT devices.
