I'm new to openvpn and feel confuse on openvpn connection configuration: ovpn over tcp or ovpn over udp
First of all, here is my understanding on how ovpn works. please correct me if wrong
It takes advantage of virtual network device.
Application works with virtual network device to send data, while ovpn encrypt them and send to physical device.
Because virtual network device provide tcp/ip stack, it'll ensure data reliability if application using tcp regardless of what ovpn used.
So I think udp for ovpn is natural choice. Besides, ovpn with tcp may cause tcp flooding. I can't come up with a scenario for ovpn with tcp.
Is it right? Do I miss any scenario?
