So, in a university network with captive portal they seem to block Wireguard and Shadowsocks just fine, Wireguard can only operate under UDP over TCP obfuscation, which, as you know it's so slow.
For the first time today I wanted to give OpenVPN a try, it didn't work as Wireguard, but enabling OpenVPN bridges, and selecting a bridge server let me connect with a better and stable speed (with UDP over TCP, it's not stable at all, speedtest can even fail randomly in the middle, or any other process)
So, how do you retire OpenVPN while not providing a solution like this under Wireguard?
