Wireguard only supports UDP. The main reason being TCP over TCP is extremely slow.

You could try OpenVPN, I think that has a TCP mode though, as said, don’t expect good performance.

For my setup, I used UDP port 443. For the vast majority of situations it works well as TCP 443 is for secure internet traffic. It seems admins often blanket 443 port open regardless of protocol 🙃

I’ve never tried this myself, but the docs have some ways of maybe getting into working https://www.wireguard.com/known-limitations/#tcp-mode .

The udp2raw repo has the following description:

A Tunnel which Turns UDP Traffic into Encrypted UDP/FakeTCP/ICMP Traffic by using Raw Socket,helps you Bypass UDP FireWalls(or Unstable UDP Environment)

Try UDP port 123 sometimes that goes through the firewalls
