Low end VPN’s and equipment are unstable and sometimes require tweaking, it is worth creating a second user, just for testing .
Do not worry about screen dump for now
FYI: To ensure you are using the VPN the correct way, hopefully the below will help
VPN Server vs OpenVPN Client
A server is something you connect to. A client is used to connect to something else.
The router’s VPN server lets you connect to your home network while you are not at home.
The router’s VPN client lets you connect your router to someone else’s network (for example, a VPN tunnel provider).
In a completely sane world, madness is the only freedom (J.G.Ballard).
