Yep there’s a reason I reached directly for that configuration. WireGuard uses UDP, that’s one of the first things that gets blocked.

Turns out that’s also the kind of protocol corporate VPNs use, reusing port 443 over TCP. They call those “SSL VPN”. They get to weed out all commercial VPNs used to bypass their firewalls as well as most torrent/game activity while still mostly catering to their business guests.
