The port forwarding diagnostics you’ve provided suggest that UPnP is not properly configured on your router or not working correctly.

Please try the following steps in order:

• Reboot your Roon Core and networking gear (router, modem, switches, etc.)
• Try to enable UPnP/NATPMP in the web administration interface for the router
• Try to manually open the port in your router’s port forwarding configuration
• Make sure the IP/Port matches the Port listed in Roon → Settings → ARC
• Check for any VPNs or Firewalls that might be interfering
• Try to update your router firmware
• Check if your modem is in Bridge mode and if not, try to place into Bridge mode

If you continue to experience difficulties, please tag the support team and include the following information:

1. What is the make and model of your modem and router? Linksys WHW03v11
2. Do you have any additional network hardware, like additional routers or managed switches? Please confirm that there are no other devices.
3. Who is your internet service provider and what is your geographic region? T-Mobile Region?
4. Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both? No

Thanks!
