Wireguard not able to ping all LAN:s

[enmi]

Hi, I have setup a VPN solution with Wireguard, that connects two different lans to our head office, (see attached network drawing)

I have also added these rules to the LAN and Wireguard interface. (see attached images)

The issue I'm having is that i can ping from my server at 172.16.10.10 to 10.0.22.1 and 10.0.22.7
I can not ping from my server 172.16.10.10 to 10.51.71.211

And i can not ping from either 10.0.22.1 to 172.16.10.10 or 10.51.71.211 to 172.16.10.10.

Is there a need for gateways an static routes to get this to work?
