Hi @Christopher_Newell,

Welcome to the Roon Community.

When i look at your error message, i see that your external router ip starts with 100. The first thing that comes to my mind, is that your ISP has implemented CG-NAT.
Please take a look at below website on what CG-NAT is and how you can check if it’s implemented.

Kind regards,
