Does this program convert UDP to TCP?

[jpmvferreira]

I'm interested in establishing a Wireguard connection when inside a very restrictive firewall, which I believe blocks UDP traffic, and also has deep package inspection, although I haven't checked thoroughly.

Therefore, I would like to ask you:

1. Does this project convert UDP to TCP?
2. In an issue on this repository you mentioned that converting UDP to TCP is a bad idea. What would you suggest be done to bypass firewalls with these kind of restrictions?
3. Does Shadowsocks convert UDP to TCP?

To elaborate a little bit further on what I'm looking for, I am interested in using Shadowsocks to tunnel my Wireguard traffic. The reasons for that are:

1. My server's firewall is completely open to authenticated WG machines
2. Each device has an IP attributed by WG which I know by heart
3. I could tunnel all of my traffic via WG, creating a full VPN home, which would be obfuscated by Shadowsocks, making it very secure and private

If neither this program nor Shadowsocks converts UDP to TCP (or I end up going for Shadowsocks even though it does not perform that conversion), I can always chain this another program that does it, and have something that looks like:
Client: Wireguard -> UDP2TCP -> Shadowsocks -> Internet
Server: Internet -> TCP2UDP -> Wireguard
So far, I've found two programs that do this (not sure if there is a universally accepted recommended one):

• https://github.com/mullvad/udp-over-tcp
• https://github.com/wangyu-/udp2raw

https://github.com/SagerNet/sing-box implements a generic UoT encapsulation that works with most of its supported proxy protocols. You could use it with a tproxy or tun inbound to proxy all traffic.

Thanks for the reply. Do you happen to know how would it compare against chaining Shadowsocks with something like UDP2TCP? This software seems to be doing more than what I wanted to, and the UDP to TCP protocol is proprietary, which I would like to avoid.
Also, could I assume from your answer that this project does not support UDP to TCP?
