+   Router/Firewall port redirs:  If you are doing port redirection at
+   your router to an internal machine running x11vnc AND the internet
+   facing port is different from the internal machine's VNC port, you
+   will need to apply the PORT applet parameter to indicate to the applet
+   the Internet facing port number (otherwise by default the internal
+   machine's port, say 5900, is sent and that of course is rejected at
+   the firewall/router). For example:
+  https://far-away.east:443/?GET=1&PORT=443
+
+   (actually, in this case the first ":443" isn't needed because that is
+   the default port for https; it would be needed for any other port). So
+   in this example the user configures his router to redirect connections

+   machine running x11vnc.

+In \fB-ssl\fR mode with the Java applet retrieved via HTTPS:
+when the HTML file containing applet parameters
+('index.vnc' or 'proxy.vnc') is sent do not set the
+applet PORT parameter to the actual VNC port but set it
+to "port" instead.  If "port" is not supplied, then
+the port number is guessed from the Host: HTTP header.
+.IP
+This is useful when an incoming TCP connection
+redirection is performed by a router/gateway/firewall
+from one port to an internal machine where x11vnc is
+listening on a different port. The Java applet needs to
+connect to the firewall/router port, not the VNC port
+on the internal workstation. For example, one could
+redir from mygateway.com:443 to workstation:5900.
+.IP
+This spares the user from having to type in
+https://mygateway.com/?PORT=443 into their web browser
+(note 443 is the default https port; other ports must
+be explicity indicated: https://mygateway.com:8000/...)
