hi all,
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?
