UPnP Port Forwarding for Java couldn't be any easier!
WaifUPnP is an extermely lightweight Java library that allows you to:
- open/close TCP/UDP ports
- check if there's an UPnP router available
- check if a port is already mapped
using literally 1 line of code, as it should be!
It's as easy as:
UPnP.openTCP(<port number here>);
Usage Examples are included.
To compile, import the project in Netbeans. Alternatively, download the binaries from http://fdossena.com/?p=waifupnp/index.frag
Once you have the .jar files:
WaifUPnP.jarinto your application
- Optionally, import
WaifUPnP-javadoc.jarif you need JavaDoc
WaifUPnP-sources.jarcontains the source code and should not be imported into your project
Java 6 and newer
WaifUPnP is a very basic implementation of UPnP, that only scans for the default gateway, and can only open/close ports.
While this is enough for most people, if you need a full implementation of UPnP, you should take a look at Cling
