UDPspeeder VS udp2raw

It's been a while since I set it up, but iirc I ended up going with https://github.com/wangyu-/UDPspeeder

Pretty sure I used the suggested config and it's been working flawlessly in the background.

Or something like that. With wireguard, it's just a matter of pointing the config at the local socket for the fec tunnel (or any other type of tunnel, there was a dicussion about making it look like TCP http traffic the other day), so it's pretty much plug and play.

I just use nbd-server, nbd-client (kernel module nbd). While at home things are fine, when not at home things can get bad unless you use something like UDPspeeder <https://github.com/wangyu-/UDPspeeder> then you just need to deal with slower speeds.

I do backups with borg while connected through ethernet.

The good news is you can implement some kind of ghetto error-correction at a higher level. Set up a tunnel to your pbx with a VPN which supports FEC -- something like UDPspeeder and configure it to send duplicates or triplicates of every packet. In this case, you're sacrificing bandwidth to improve reliability.

All it needs is a bit of reed solomon encoding in the transport for additional reliability https://github.com/wangyu-/UDPspeeder

Maybe udp2raw https://github.com/wangyu-/udp2raw

For that, I was going to setup UDP2RAW on my laptop to convert Wireguard's UDP traffic to TCP, send that TCP traffic to my server via port 22, to pretend it's SSH traffic, in the server setup UDP2RAW to convert that TCP back to UDP and send it to the Wireguard interface.

I've been doing some research and apparently, there's there are methods to obfuscate the VPN connection but everything I've looked at until now requires a special config on the server side of the VPN as well as the client side, and I haven't found anything related to Windscribes configuration for obfuscated servers via OpenVPN Scramble, Shadowsocks, obfsproxy, UDP2RAW, etc.

I read lots about this, e.g. the howto here. What I try to achieve is similiar to this setup here but the udp2raw server and client position should be switched. Is this possible somehow?

It's fair, though I would consider using tools like (for example) udp2raw for both OpenVPN and Wireguard if you need to bypass firewalls. Running OpenVPN in TCP mode is an awful experience.

Try to use udp2raw to hide the protocol https://github.com/wangyu-/udp2raw

check various ports with netcat as other mentioned. When you find a port you think may be open try it out. Additionally... this is all UDP and is EASILY blocked with deep packet inspection... you don't even need to go that deep into the packet... You could try a different VPN, or you could try to wrap your WireGuard into a TCP stream : https://github.com/wangyu-/udp2raw
