The default configuration works with UDP daemons on port 1194, TCP daemons on port TCP 443, and the web services on TCP 943.
This default configuration works fine with the Connect Client.
If you change port settings, all clients must be reinstalled to get the updated configuration.
If you somehow try to squeeze your own web server in here and use port-sharing to redirect to that, you will cause problems with the API that Connect Client and Access Server use to communicate. If you do this, you will need to switch the Connect Client to advanced mode and manually install a user-locked or autologin profile, instead of relying on the built-in API to negotiate with the Access Server for a connection profile.
