Thank you for the reply !
I tried the simple router of ASUS it was working fine both sides (Local/Remote) without any configuration on the router or NANO devices.
Therefore i believe the problem reside in OPNsense configuration.
Any suggestion to trace the IP packets ?
FYI: The nano is forwarding DHCP from OPNSense, it does not act as DHCP server for any side.
