Description of Issue -

What is the exact port forwarding error message you see in the Roon Settings → ARC tab?

{
“connectivity”: {“status”:“NetworkError”,“status_code”:504,“error”:“error: Error: ETIMEDOUT, response code: undefined, body: undefined connected? undefined”},
“external_ip”: {“actual_external_ip”:“92.40.72.3”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.8.1”,“found_upnp”:true,“error”:“Did not find UPnP service with WANIPConnection on network”}
}

Have enabled Upnp within router settings and toggled on and off with no luck.
NAT mode on router settings is set to cone.
Changed the IP address from using DHCP to manually and replaced with the Roon Core IP within my Mac Network settings with no luck

Any help appreciated

I suggess you have a look around over there. Here’s an example thread: VPN: step-by-step I also recommend looking into TailScale, a more robust proxy solution: Tailscale implementation with ARC to c…
