Trouble locating UPnP settings for Roon ARC port forwarding (ref#1FC6WA)

Network Setup

· My only router was provided by my ISP

ARC Status

· ARC is *Not Ready*

Roon Error Code

· “Did not find UPnP service with WANIPConnection on network”

Have you successfully located and enabled the UPnP or NAT-PMP settings in your router's web UI?

· UPnP is not listed in my router settings

· How would you like to continue with the network configuration?
I would like to try and find a solution for UPnP/NAT-PMP on Roon Community

Describe the issue

I'm trying to set up my Roon ARC with my laptop PC as a Roon core server. I'm having trouble finding UPnP in my server settings so I can set up port forwarding.

Describe your network setup

My ISP is AT&T. My router model number is BGW320-500. My Roon core is my laptop PC, the model number of which is ASUSLaptop_Q540VJ. My router and PC are connected through WiFi. I've installed ARC on my iPhone.

Hello @mitchrusso, welcome to the community!

The AT&T BGW320-500 does support UPnP, but it is not labeled obviously in the interface. Here is where to find it:

  1. Open your browser and go to http://192.168.1.254
  2. Click on Home NetworkIP Passthrough — if you want the cleanest ARC setup, you can enable IP Passthrough to your laptop, though this requires a static IP on the PC
  3. Alternatively, go to FirewallNAT/Gaming and manually add a port forwarding rule for the port shown in Roon ARC settings (usually 55002) pointed at your laptop’s local IP address

Note that on the BGW320-500, UPnP is often disabled by AT&T by default and cannot be enabled by the user — it is locked in the firmware. Manual port forwarding via NAT/Gaming is therefore the recommended approach for ARC on this router.

One more thing: since your Roon Core is running on a laptop connected via WiFi, make sure the laptop has a reserved/static local IP in the router settings so the port forwarding rule always points to the correct address.

Hi @mitchrusso,

AT&T hasn’t commonly implemented CG-NAT so we can likely resolve this with the port forwarding settings changes suggested above.

Specifically, you’ll need to try to create a manual port forwarding rule in the AT&T router settings admin page. This is usually under the NAT/Gaming tab under Services.

This rule should be TCP protocol. Both the internal/external port numbers should match the port assigned in Roon Settings → ARC, and the IP address should also match.

Let us know if this helps. Thank you!
