Hi, Roon ARC app not conencting to Core. I use Roon Nucleus as Core and have a Technicolor DGA2231 Router acting as Modem (wireless disabled, Callflow/Trooli service provider), Connected to Google Nest Wifi Mesh system. Can’t work out how to get ARC to work after reading the walkthrough/troubleshoot section of ARC. thanks
It looks like you’ve got a double NAT situation. Basically you have both the Technicolor Router and the Google Nest WiFi acting as a router. The easiest solution would probably be to see if you can set the Technicolor Router to something like “bridge mode.” Alternatively you could put your Google Nest into bridge mode.
Please see the staff response in yellow above; your description suggests you might also be encountering a double NAT layer in your local network.
I recommend glancing through the Help Center article listed above. If the article doesn’t help illuminate your particular situation, please reach back out, and we’ll happily split your post into a separate topic thread to continue to troubleshoot.
Thanks for your message. Double NAT was indeed the issue. I tried to make my ISP router/modem the “bridge” manually but ran into a lot of problems. After calling my ISP they made the changes for me and now Roon ARC works with my ISP router and Google Nest Wifi Mesh. Thank you for your help. Problem solved
Instead of setting one of the routers into bridge mode, just add a port-forwarding rule in the router connected to the internet by adding port 55000 or whatever you prefer directing to your second router. Just make sure Roon core has the same port (settings → roon arc) at the right bottom of the page.
…and if not needed from elsewhere: disable UPNP again
I’m based in the UK. So different ISP. Mine is callflow/Trooli.
I think they basically set my ISP router to bridge mode. I already had the wireless disabled on my ISP router so it didn’t interfere with my mesh, but clearly there was more to be done. Like others have said, it is probably easy to do without help, but it was beyond me.
Does your Google Nest Mesh system have multiple points and, if so, did all the features still work? I’m getting conflicting reports about whether bridging the ISP router/modem will interfere with some of the features of a multi-point Mesh system. Thanks!
Hi. Yes my google nest mesh has multiple points. I did not change anything related to the google nest system. In fact, you can set the main google nest router to Bridge Mode but this is not recommended as it does not allow you to use the mesh system if you do this. You need to put the ISP router into bridge mode. Don’t touch the google nest mesh if it is already working for you.
Please don’t do this. You’ve just opened up the device at 192.168.1.136 to the entire internet, not just a single port. To give you an example: if the device is a nucleus, the entire internet can reach data share via the SMB protocol. People have been hit by ransomware by doing exactly what you are doing now.
