Port Forward From Android Device on any Internet Gateway Device (Router) that has the UPNP option enabled. First step in opening a port on a IGD si to enable the UPNP option, for this you need to access the router settings and select this option
Application screenshot:
For own implementation use upnplib-mobile.jar library.
First the IGD (Internet Gateway Device Router) using the following line of code.
InternetGatewayDevice[] internetGatewayDevices = InternetGatewayDevice.getDevices(5000);
If the internetGatewayDevices array is > 1 get the first element and use the following methods.
firstIGDEmelent.addPortMapping(description, externalRouterIP, internalPort, externalRouterPort, internalIP, 0, "TCP");
firstIGDElement.addPortMapping(description, externalRouterIP, internalPort, externalRouterPort, internalIP, 0, "UDP");
Both protocols (TPC & UDP) are required.
This library also has the remove implementation with the following methods.
firstIGDEmelent.deletePortMapping(externalIP, port, "TCP");
firstIGDEmelent.deletePortMapping(externalIP, port, "UDP");
Application developement in progress.
