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.

Thank you! That’s very helpful to know. First time I’ve even heard of things like this but when using low quality networks I can see how this would be great!
