6.1.2 Port forwarding
Introduction
Port forwarding allows you to forward incoming Internet traffic arriving on a specific port to an internal IP address.
For example: if you are running a web server and the Gateway receives a request on port 80, this request should be
forwarded to your web server.
Use a reserved IP address
The target device of the port forwarding rules will be specified by an IP address. Make sure that your device uses a fixed IP
address. If you do not do this, the device might get a new IP address after some time and the port forwarding rule will no
longer be applied to the device. For more information, see
6.2 Assigning a reserved IP to a device
