Description of Issue

Auto config did not work on ARC. I have set up my K50 with a static IP address and port forwarding using your instructions and it still can’t connect. Here’s the error code -
{
“connectivity”: {“status”:“NetworkError”,“status_code”:502,“error”:“error: Error: connect EHOSTUNREACH 97.115.225.234:55002, response code: undefined, body: undefined”},
“external_ip”: {“actual_external_ip”:“97.115.225.234”,“router_external_ip”:null},
“natpmp_autoconfig”: {“status”:“NotFound”},
“upnp_autoconfig”: {“server_ip”:“192.168.1.1”,“found_upnp”:true,“error”:“<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/\” s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/\“><s:Body><s:Fault>s:ClientUPnPError<UPnPError xmlns="urn:schemas-upnp-org:control-1-0">501ActionFailed</s:Fault></s:Body></s:Envelope>”}

Hi Chris,

Can you provide the following details about your network setup to help expedite troubleshooting?

  1. Who is your internet service provider?

  2. Please list the make and model of your modem and router?

  3. Do you have any additional network hardware, like additional routers or managed switches?

  4. Does your network have any VPNs, proxy servers, or enterprise-grade security?

  5. What machine are you using as a Roon Core, and how is it connected to the internet?

Thanks!

So you have a potential double Nat, one router behind another, issue. Can you set one of them to be in bridge mode?

The satellite is not another router, it is a four port switch. The Orbi router is connected to my modem

Thanks - I followed those instructions before posting here.

Is the Zyxel C3000Z in bridge mode? If not you have 2 routers and thus a double NAT.

I think that’s the issue. I’ll look into this. Thanks
