UPnP stands for Universal Plug n Play, This is the pussy/easy method for applications to port forward information. This can be useful for when your parents are dicks and don't let you have the router login info. Resulting in you not being able to port forward your Minecraft/website server. So you use UPnP tools to basically say to the router "Yo i need to open some shit for a short amount of time" (UPnP ports are reset once the router looses power, or become ineffective when your server gets a new private IP address)
