Internet port mapping on your modem

Port opening or forwarding is sometimes requested by certain software and peripherals such as games, home automation equipment, etc.

Port opening requires that the software or peripheral requesting the port opening, communicates the port numbers it would like to have opened.

NB: Port opening makes your network vulnerable to external traffic. Proximus is not responsible for the results caused by opening and forwarding ports.

Our technical service does not provide any support for this matter.
