My work WiFi blocked traffic to port 51820, the default WireGuard port. I was wondering why my VPN started failing to handshake one day. I changed my ports to 51821 that night and back in business. I checked our technology policy and there’s no “thou shalt not use a VPN” clause so no clue why someone one day decided to drop WireGuard traffic on the network.

Restrict use of private devices?

Though just blocking particular ports for this purpose is very 90s and obviously ineffective, as you demonstrated. Anybody proficient in installing wireguard also knows how to change ports.
