Always on VPN Device Tunnel - Client Firewall

Hi.

I have set up Always on VPN, device tunnel.. The clients auto connect and can access everything on the LAN fine.

But i can't seem to connect from the LAN to the remote client, I've got Windows firewall logging, and i can see the Ping / other traffic is dropped on the client. I've tried creating an Allow rule, but still the traffic is blocked, Disabling the Windows 10 firewall on the client, and it still doesn't work.

Is there anything on the VPN tunnel settings or rules else where that blocks LAN traffic over the VPN to the client? 

Thanks,
