The IP 82.117.x.x belongs to the network router, not your machine. Your machine has only LAN IP which starts with 192.168. You are required to setup port-forwarding on your router to forward all request on specific port (e.g. 8080) to your machine. As well, make sure that you have static IP or setup some dynamic DNS service.
Generally speaking, you are required to perform the same steps as for configuring any web server to be available from WAN.
