Port Forwarding allows you to make a device or service in your home network accessible by the other devices over the internet, whilst ensuring your network remains protected.

Different services use different service ports, such as Port 80 is used for HTTP service, port 21 for FTP service, port 25 for SMTP service and port 110 for POP3 service. Please verify the service port number before the configuration.


Here we take Deco M9 Plus as an example.

Launch the Deco app, tap More at the bottom right corner, then click on Advanced.

Choose Port Forwarding.

Tap Create or the Add icon at the upper right corner.

Choose a Service Type, type in the Service Name, and tap Internal IP to select a device you want to open ports for, then type in its External Port and Internal Port (Service Port). Tap Done.

If you leave the Internal Port blank, the internal ports will be the same as the external ones.

For example, set up the External Port as 4500-5000, then leave the Internal Port blank, tap Done. In this case, the internal ports 4500-5000 will be opened automatically.

After setup, please go back to the Advanced page, tap IPv4 and check the WAN IP address of the Deco system. Now you can try to use WAN IP:Port Number (External Port) to access the service from the outside network.


If the WAN IP address of the Deco is not a public IP address, but a private IP address, that means there is another NAT device connected to the WAN Port of the main Deco. You need to open the service ports on that device as well.

For how to verify the IP Address is a public one or private one, please refer to this link:
