What is Port Forwarding?
Port forwarding (opening ports) allows you to open specific ports in the router's firewall which are needed by some services to communicate to devices on your network. A port has an internal and an external value called the port number. Multiple external hosts can use the same external port number, but each internal port must be different, this allows Network Address Translation (NAT) to identify the destination for inbound traffic.
Port forwarding is necessary when you are having issues related to a restricted NAT.
Where do I find Port Forwarding settings?
UPnP allows services to automatically set up port forwarding rules, although you can also manually set up port forwarding. Manual set up can be tedious if you are setting rules for multiple services and multiple devices. You should not enable UPnP and set up port forwarding at the same time.
Because you are opening/forwarding ports in the firewall, this setting must set in the router. If PLume is in bridge mode, you will need to set up port forwarding rules in your router. If you are using Plume in router mode, port forwarding can be set up in the Plume app:
- You need to set an IP reservation for the local device.
- From the IP reservation, tap on Open Port.
- Enter a name for the rule (each name need to be unique).
- Enter the External Port number the service requires.
- Enter the Internal Port number* to be used on the device.
- Use the same number as the external to just open the port or another number to route the traffic to a different port.
- Choose the required Protocol.
- Tap on Save.
- Repeat these steps for each rule needed.
- If the external port has already used for one service, it is not necessary to set it again for a different service on the same device.
- The external port number for each rule can be the same, however the internal port number must always be unique. This means you will need to choose another internal port number for each local device.
