UPnP or NAT-PNP support

UPnP and NAT-PNP protocols provide automatic port configuration features for various routers (gateways). Some routers have these features enabled by default, some have not. It allows apps on your device to open ports on your router when needed and to close them when they are stopped.

Determine your NAT type

Before you make any changes to your router settings, you need to make sure those changes will actually solve the issues you experience while using Mysterium node. To do that, take a look at your NodeUI dashboard's current NAT type status.

To check the status and your NAT type on your Mysterium NodeUI:

  1. Open NodeUI and navigate to Settings.

  2. Select Advanced > NAT Traversal order > Accepting connections > Hover on "i" icon.

If there is an issue with your network capabilities, current NAT status will be limited. That means other peers might struggle connecting to your node service.

There are three possible NAT types: open, moderate, and strict. Each type provides a different level of network security and affects node operations in a different way.

  • A strict NAT provides maximum anonymity and network security. It limits connectivity with other peers, particularly those who also have a strict or moderate NAT on their network.

  • A moderate NAT provides some anonymity and network security. It lets you connect to other peers, but limits some functions. You may not be able to join p2p channels if you have a moderate NAT.

  • An open NAT doesn’t provide any anonymity or additional network security. With an open NAT, you will be able to connect to any peer on Mysterium Network.

Enable UPnP in your router settings

To enable UPnP in your router settings:

  1. Type your router’s IP address into the address bar of a web browser. Most routers have the default LAN IP address 192.168.0.1 or 192.168.1.1, but here’s a full list of default IP addresses.

  2. Login to access the setup page. The default password is usually “admin,” but here’s a full list of default router passwords.

  3. Each router manufacturer arranges its setup page a little differently. Look for UPnP menu in the settings. Contact you router manufacturer if you need assistance.

  4. Open the UPnP menu and enable UPnP.

  5. Save changes before exiting your router settings.

  6. Restart node service.

For heightened security, use manual port forwarding instead

While it’s far easier to set your NAT type to open by enabling UPnP in your Router's settings, it does open your internet network up to potential security breaches. If you prioritize your network security over convenience, consider setting up port forwarding manually instead.
