Lighthouse

Lighthouse Publisher's Description:
Lighthouse is a dynamic port forwarding utility, allowing you to enable and disable port forwardings with just a single click. Both NAT/PMP (Apple Airport base stations) and UPnP (D-Link, Linksys, Netgear) protocols are supported.

Port forwardings are frequently necessary for tools such as instant messengers, file-sharing utilities and other networked applications that are run from behind a NAT gateway (read: a home network router). Being able to dynamically manage your port forwardings saves you from all the hassles of having to deal with cumbersome static forwardings.
