Controls the udp port setting for WireGuard VPN Client & Peer Key Generator in real time.
Clients will not know what IP/hostname to connect to without an Endpoint.
WireGuard UDP port must be an integer between 1 and 65535 (default: 51820).
WireGuard MTU is typically 1420 (Ethernet) or 1280 (IPv6 minimum). Values above 1420 may cause packet fragmentation.
