so I have a successful connection from client to server ... question is How do I use this connection ? I am on a Ubuntu 19.04 desktop ... using other vpn approaches once a successful connection is made applications like my browser just automatically start using the vpn connection however once above connection is made my browser just times out

Sequence of events ... I ssh onto my remove machine and launch your server from a terminal ... then I launch my client in another terminal ... once a good connection is made I can see ongoing logging shown in server terminal window so I still have connectivity to that remote machine via ssh ... Problem is any browser I use just times out ... from a new terminal things like ping fail to connect ... evidently the vpn connection my client has made is not being made available to my applications
