After weeks and weeks of figuring this out I finally was able to use Roon Arc on the go… had a network maintenance which prevented me from using the app… I rebooted the Nucleus, did some test at home using 4G then went out and BOUM its finally working! Lots of patience and to be honest I thought I …

Well, they don’t seem to know what I ask for, and I really don’t know how to ask in a way that they would understand. All of this is spanking new to me. A few days ago I was vaguely aware that there are somethings called ports in a network, and now I desperately try to get a grip.

OK, seems like the thing to do. I’ll start over

[image] Mikael_Ohlsson: Zyxel EX3301-TO Is this the only router you have in your home network? If so, then the muliple NAT situation is down to something that your ISP is doing upstream. Second question, is the Zyxel connected to your telephone landline, or is it connected to a 3G mobile net…

I also suspect that it’s a Case B senario. The only recommendation I can find in the document is to get a Static Public IP-adress. I have got one, so I think that I need something else to try

Zyxel is the only router. It’s a fiber optic connection. Bahnhof says that they do not perform NAT from the Optic to Ethernet modem. Earlier I got rid of the multiple NAT error when I closed VPN, but it’s off now. I have had four support calls to Bahnhof with four different technicians. I will tr…

[image] Mikael_Ohlsson: Bahnhof says that they do not perform NAT from the Optic to Ethernet modem. That tells me that your support person at Bahnhof does not have a full understanding of the technology they are using… :roll_eyes:

Well, that’s a concrete question, that I can ask when I call. I certainly hope that that it’s the right one since I now pay extra!

I suppose so. But they do go and ask some colleagues sometimes if they are stumped, so they do try, I think

I had the same problem. Behind a CGNAT. I found a solution and put it in this thread, maybe it can work for you. https://community.roonlabs.com/t/tailscale-implementation-with-arc-to-circumnavigate-isp-cgnat/215356
