I set up my own VPN by installing OpenVPN on a Ubuntu server, then I download
client.ovpn file from Ubuntu server to my Windows laptop. And then, I import that
OpenVPN GUI app on Windows and finally, I connect to my Ubuntu VPN server and everything work fine.
I installed OpenVPN on Ubuntu server using this instruction: https://github.com/angristan/openvpn-install
So I think traffic flow will be like this:
My computer (browser,...) --> Ubuntu OpenVPN server --> Internet.
Does OpenVPN GUI encrypt traffic between my computer to Ubuntu OpenVPN server?
