443 TCP HTTPS access. Port 443 is enabled by default for
client connections. Port 443 can be changed.
Connection attempts over HTTP to port 80 are
redirected to port 443 by default, but port 80 can
service client connections if SSL is off-loaded to an
intermediate device. You can reconfigure the
redirection rule if the HTTPS port was changed.
See “Notes and Caveats for TCP and UDP Ports
