I am really stuck on this one - please help. I have an openVPN server running on Ubuntu 18.04.
I have a Macbook running as a client.
The Macbook connects to the VPN server without problems if it does it through the same ADSL router using the Ubuntu ip 10.0.0.3.
If I try connecting through an alternative network connection - say an iPhone hotspot I can't connect.
Logically, the Macbook client needs to know how to connect to the VPN server if it is not connecting through the same LAN as the server. How do I achieve this? How can the Macbook "find" the VPN server if its not on the same DSL router
