The MiniUPnP daemon is an UPnP IGD & PCP/NAT-PMP daemon for gateway routers.
UPnP IGD & PCP/NAT-PMP are used to improve internet connectivity for devices behind
a NAT router. Any peer to peer network application such as games, IM, etc. can
benefit from a NAT router supporting UPnP IGD & PCP/NAT-PMP.
