UPnP

Universal Plug and Play (UPnP) is a network protocol that allows compliant devices to automatically set port forwarding rules for themselves.
This application can automatically open some ports on your router to allow you to access server from outside of network.

This feature will only work if your router connects to the Internet with a public IP address assigned.
Currently, most of mobile networks don't support UPnP.

Please make sure that router supports UPnP and it is enabled!
