3.3.2 Port forwarding
You can open manually the ports in the router. It is necessary that your device
(computer, videogame, etc) has a static/fixed IP address.
Please note: the (possibly empty) list of forwarded ports that you will find is NOT
synced with the “easy configuration user portal“. The ports that you open in one
of the web portal cannot be seen on the other web portal.
