Rock nuc i5, 16Gb RAM on SSD
Deco x55 router
ISP Altel, double NATed ip4, native support ipv6
ip4 double NATed and can’t be used.
Added firewall rule to router IPv6 and Roon immediately tell it’s OK for Roon ARC. But it just not gonna work.
BTW: just added external access to my QNAP NAS thrught ipv6 and it working well.
Who is your ISP? IPv6 pinholing won’t work with all DS-Lite configurations. If you have true dual stack with your ISP and router setup, then you’ll likely need to manually pinhole in your router configuration.
The port forwarding configuration test in Roon → Settings → ARC doesn’t ping the phone - it just verifies the upstream connection through the opened port/pinhole. If your cellular provider is filtering the downstream connection in any way, you’ll need to pursue a VPN solution in Tinkering.
We wanted to check in since some time has passed, and I noticed you’d posted and deleted a comment on this thread.
Your particular service provider might have an implementation blocking ARC on IPv6. It’s worth reaching out with your intended use case to see what options are available - they may have a dedicated IPv4 address available.
Were the above instructions helpful at all?
I have conducted some tests on my own: I moved Roon from my Rock Core to my QNAP NAS due to the absence of IPV6 settings in Rock. However, I am still facing issues. While I can connect to NAS services using the same IPv6 address (using various ports such as 8081, 8080, 445, 8080, 443), I am unable to connect to Roon on any port. I attempted to use Putty, but only encountered a black screen. I have experimented with different ports and addresses multiple times and have grown weary of updating DDNS in my post, so I decided to delete my post.
I am able to connect remotely to Phillips Hue, NAS, and Alexa, so it appears that the technology behind RoonArc might not be ready for use. While I could pay my ISP for a “white” static IP, I don’t believe it is worth it.
The symptoms you’ve described sound like your ISP has implemented carrier-grade network address translation. Outside of the dedicated external IP address you mentioned, please note that ROCK and ARC are IPv6 capable, but only in a true dual-stack or otherwise properly prefixed setup.
You may need to add a pinhole if you’re relying on IPv6. In any case, you’ll need to inquire with your ISP what their specific implementation might be.
