Or will it also work with an Automatic IP? I see a lot of threads where they say: switch to Static IP. Well, that’s not an option for me. My ISP can only give me a static IP when I get a Business Account, and that costs more…not worth it. So, please tell me it also works with Auto-IP’s

The solution to my problem can be found in this document: [image] Open it up and at the bottom you will find this: [image] I found out that when you activate UPnP, I don’t have to do a Port Forwarding, but when you do, you have to deactivate UPnP… strange, but that’s how it now works here/ So…

What else would the IP address be? (Very green behind my ears…)

[image] JST1963: ConflictInMappingEntry Could it be that your Port forwarding rule is conflicting with the port uPnp finds? Perhaps try deleting the port forwarding rule and rebooting your router and see what uPnp does.

Maybe I didn’t word that well. The IP address in the port forward rule will need to match the IP of your Roon core server. Roon will show this in the Roon ARC settings page next to where the ARC port is entered. Your diagnostic messages don’t contain “multiple_nat” so I think that can be crossed of…

I just deleted what you proposed…rebooted the router…(my wife griped about it because she lost the connection with the TV)… And you’re not gonna believe it, now I get the multiNAT error: { “connectivity”: {“status”:“NetworkError”,“status_code”:502,“error”:“error: Error: connect EHOSTUNREACH 81.16…

You do indeed have an external IP address, otherwise you could not be on the Internet. Type “what is my IP address” in your browser and you will find out what it is, or currently is if your ISP issues Dynamic IP Addresses.

So you know that Roon reaches your modem. Can you give us info on your network setup? 1 Which ISP? 2 Make and model of the router? 3 Do you have additional network gear?

All is connected using the following: Internet (ISP: Telenet Belgium) To ISP modem (DOCSIS 3.1 WIRELESS (DOCSIS)) Firewall active UPnP active No port forwarding DMZ address exists but is not used in Asus Router) To Asus RT-AC68U router (FW: 3.0.0.4.386_49703 Setup as Wireless router mode / AiM…

It appears you have two routers which both do NAT. Do you use both to connect devices? Wifi or ethernet?
