Those protocols are almost all TCP-only and not UDP. On such networks it's useful to also support TCP connections, even though this is less ideal due to the possibility of the TCP Meltdown phenomenon. But given the choices between something that works reasonably well or not at all, we've chosen to be practical and also support TCP. By default we choose the port TCP 443 which is the same port

TCP vs. UDP (In-depth Look) So what is the difference between TCP and UDP, exactly? We took a quick look at their differences before, but let’s see what they all mean.

SSL VPN over UDP still attempts to connect to the VPN server on port 443, but unlike HTTPS traffic that uses TCP as a transport protocol, it uses UDP.
