OpenVPN connects but not pingable

[eix0r]

Hey so I set up an OpenVPN on MS2016 (*sigh*), this is a hosted server running a license server for a CAD Software.

I have two clients where the CAD Software is running which I want to be able to connect to the server to authenticate the software. So they connect to the MS2016 server which hosts the openvpn and the license server, the connect works but they cant ping each other. If I turn off the firewall on the client I can ping from server -> client but not the other way around. Any ideas how I can fix this without turning off the fw?
