Note: The local IP address of the Mac hosting WeatherCat should be a static IP on your network. If you allow DHCP to dynamically set your local IP address, it could change over time when you have to reboot, which will break the forwarded ports. Use the DHCP Reservations feature in Airport Utility | Network to reserve a static IP address for your host Mac.
