You can use the information in this post to see exactly what connection information is being published by your server:
As to how that information is determined, it depends. My experience is that it populates the list from:
- Any interfaces on the local server which have a default gateway defined (or the specific interface specified in the server’s network settings).
- Any custom server access URLs configured on the server.
- (If remote access is enabled) The server’s detected public IP addresses. “Detection” here means what it determines to be its external IP addresses.
For each, the port used for the connection can be configured, except for the local interfaces; those will all use 32400.
I’d check what is being published and see if that matches your expectations.
