Using Port 443 for MGMT Access and SSL VPN Scope: Accessing the FortiGate's management page and SSL VPN on TCP port 443 By default this is not possible as port 443 can only be assigned to one system service. Since SSL VPN and HTTPS administrative access are two different system services a workaround is required. Requirements:
Oct 14, 2011 · VPN use of Port 443 Hello Community, Most of my users are behind tight firewalls at remote locations, which do not allow the standard vpn ports of 50,500,4500 to pass.

If you access SSL VPN via web portal you can add the custom port number in the URL like this: "https://mysslvpnserver.com:30443". port-share x. x. x. x 443 Where x.x.x.x is the internal IP address of the web server to which the non-VPN traffic will be forwarded. Now if OpenVPN client hits that port, it will connect and work fine, and if a web browser is pointed at the same IP and port using HTTPS, it will be connected to the web server.
So just decided to leave everything as is and live with port 443 open. I did a Shields Up test for the heck of it, and all ports were stealth. So I checked the RG's firewall, and it was set to
Port 443. This can serve to block incoming connections. Where a VPN is offering port forwarding, it reroutes the incoming connections to enable them to bypass the NAT firewall.

To make OpenVPN listen to port 443 and have other connections forwarded to your webserver, edit your configuration file and add these lines
NOTE: The default port for HTTPS management is 443, the standard port. You can add another layer of security for logging into the SonicWall by changing the default port. To configure another port for HTTPS management, enter the desired port number into the Port field, and click Apply. Our VPN service uses these ports for Firewall configuration: For OpenVPN, we allow connections via TCP or UDP protocols on ports 443 or 1194. The IPVanish software uses port 443; Both PPTP and L2TP need the PPTP & L2TP pass-through options in the firewall/router's management interface to be enabled (if applicable).
