The same openvpn process can't listen on UDP and TCP sockets at the same time. You have two good options: use two tap interfaces for openvpn. Have two openvpn server processes, one for each tap interface; one should listen on UDP, the other on TCP. Bridge these two tap interfaces on the server. use two tun interfaces.
At NordVPN, you can connect via OpenVPN both through TCP and UDP. For OpenVPN TCP connections - port 443. For OpenVPN UDP connections - port 1194. You can read more about TCP vs UDP here. How to set up OpenVPN manually with NordVPN? You can set up an OpenVPN connection manually on different devices, guides for different devices can be found here: All Major VPN Protocols Explained: PPTP, IPsec, IKEv2 Dec 19, 2019 Beginner's Guide: TCP vs. UDP VPN - Which is Better? - VPN
Jan 07, 2020 · TCP vs UDP in the different VPN protocols such as OpenVPN. OpenVPN is a protocol to create virtual private networks that allow us to ensure point-to-point communication, since all tunnel traffic is encrypted and authenticated. In RedesZone you have a complete tutorial on how to configure an OpenVPN server and connect to it easily.

I have had no problems configuring the setup, except for when attempting to use UDP instead of TCP. Whenever I use TCP as the protocol, it connects no problem. When I attempt to use TCP, connecting from a remote site through the internet to the cable modem's IP, it connects no problem.

The comparison between TCP and UDP tunnels have not been sufficiently reported in the scientific literature. In this work, we use OpenVPN as a platform to demonstrate the performance between TCP/UDP. 1. UDP vs TCP 1.1 Transmission Control Protocol (TCP) TCP is also known as the "reliable" protocol because it guarantees delivery. For each packet sent over TCP, a confirmation packet is answered by the destination server. If no such confirmation is received by the source, a new packet will be sent. When using TCP you have a guaranteed delivery Jan 18, 2019 · Avoiding TCP meltdown effect This one is a serious deal-breaker for TCP over TCP, be it used by OpenVPN or any other type of TCP tunneling like SSTP. TCP by itself is designed with congestion control and recovery in mind. It is adaptive to the condition of the link it’s running on and does a decent job in recovering from network mishaps. The OpenVPN protocol is designed to work the best on UDP, but it supports TCP. Normally UDP does not track if packets arrive at their destination. OpenVPN has a method that tracks and verifies if data reached it's destination outside of UDP. The problem that surfaces is that in TCP mode, the OpenVPN protocol still does its own outside TCP does that by using a complex assortment of metadata with explicit acknowledges and reemissions. Thus, TCP incurs a slight network overhead. If the VPN uses TCP, then your own TCP connections will use IP packets sent through the VPN, so you end up paying the TCP overhead twice. An UDP-based VPN thus has the potential for slightly better
