Please see the Node Networking guide for a detailed explanation of how and why to enable UPnP for a multi-node setup.
Node Networking
A few things to note when running option 14
Maximum on 8 nodes per public IP Address
Valid API ports are (16127, 16137, 16147, 16157, 16167, 16177, 16187, 16197)
You will need to verify your gateway's IP address when running option 14.
Toggle UPnP Mode
Enter Desired API Port
Verify UPnP Router IP Address
The install script will likely show the correct IP Address for your router, but if you have a more advanced networking setup this may need to be configured manually.
