How to set up and configure an OpenVPN Server on UbuntuHello, I have set it all up following the instructions, my MacBook connects to the OpenVPN server gets an IP etc and I can ping the server that is behind in the network that the OpenVPN server sits on. That is all good.
So the OpenVPN server is 10.0.0.5 and I have a Domain Controller on 10.0.0.4 and it can ping .5 no worries.
My VPN connected device 10.8.0.2 can ping 10.0.0.4 no problems! But 10.0.0.4 cannot ping 10.8.0.2! I feel like there is some reverse routing or something that we are missing?

The easiest way to get traffic flowing would be to configure the system at 10.0.0.4 to also have a VPN connection.
Otherwise, you’ll need to add a route for the VPN subnet on the 10.0.0.4 system to send traffic via the VPN server.
Assuming the subnet is something like 10.8.0.0/24, you’d add a route like ths on the 10.0.0.4 system:
sudo ip route add 10.8.0.0/24 via 10.0.0.5
That will at least get traffic onto the VPN server and you can then troubleshoot how it is flowing from there.
You have to uncomment the ‘client-to-client’ portion in the /etc/openvpn/server.conf file to let the clients ping and ‘see’ each other.
