An irNetBox can be used when it is behind a NAT router as long as the necessary ports are configured to pass through TCP communication to the irNetBox.

The NAT Router has to be configured to forward the irNetBox TCP traffic from the external (public) network to the internal (private) network. The TCP ports used are 10001, 30704 and 30718 which all need to be forwarded to the irNetBox.

Once these ports have been setup, start the IRNetBox Manager on a computer on the outside of NAT Router and use the public IP address provided by the NAT Router. Details of using a specific IP address to find and communicate with an irNetBox can be found here.
