How to make a connection using 2 protocols at the same time?

Question

openvpn

I want to make TCP traffic go over TCP, and UDP over UDP connection. Can this be done?
Or in the client config generally offnutb UDP tunnel

Answer 1

I don't think it's possible. what does not make sense, the developer usually tries not to implement.

Answer 2

It is possible, you raise two configs on different ports, one on udp another on tcp. For example, tun over udp works for me, and tap over tcp on the same port. Client requests are listened to by the interface.
