OpenVPN is very good. Use it if you can.

Port 443 is HTTPS. That's not SSL port. SSL port doesn't exists. It's just a protocol on top of another one (like HTTPS cs HTTP, or LDAPS vs LDAP) for securing the transmission.

443 => HTTPS, nothing related to VPN. OpenVPN use the port you want, but the default is 5000 You can use OpenVPN with UDP or TCP packets, on a user-defined port.
