Private IP address is meant to be accessed only within the LAN or intranet.
In order to access the XServer or TLServer from public internet, first you must setup the Internet router to "forward" any external incoming request to access server of the port number used by XServer and TLServer (e.g. "9080" ) to that particular private IP address. Then you when you access the public IP address of the router using the port number 9080, the request will be transparentlly sent to the XServer or TLServer with the pre-defined private IP address and responses from XServer will be sent back to the requester through the router.
