Im trying to get roon arc working and in order to do so i have to create an ipv6 pinhole through my firewall direct to the roon server, running on an oladra. the trouble is that even though my network is giving me ipv6 addresses, which are needed for arc to work with my ISP, (starlink), the oladra only seems to pick up an ipv4 address.
Roon uses port 55000 by default, but you can pick a different port if you’d like.
Feel free to use any available port in the 10,000 to 65,000 range. You’ll want to set this port in Roon, in the Roon ARC settings tab. You’ll also need to enter this port when setting any manual port forwarding rules in your router.
On my Roon ARC Page, I have a Hostname, MAC Address and Local Network Address. I am not using iPV6 and it works for me. I can see you wanting iPv6 if internet security is your concern. The fact that it works with your laptop does not necessarily eliminate ROON as the issue.
This from Roon help page:
IPv6 has been known to cause issues with network communications. Some ISPs have started rolling out IPv6 support, and customers in those regions have had issues communicating with our services. We recommend disabling IPv6 on the router and all devices.
i use starlink for internet which has issues with arc, so i have to use ipv6, if the antipodes server used ipv6 i would be sorted but it doesnt and i dont understand why
This shows that Roon is listening via IPv4 in this example. While it is true that your laptop has reserved an IPv6 address, it doesn’t appear from this that Roon is actually using it for ARC.
What leads you to believe that an IPv6 address on the Oladra would solve your problem? Roon is listening on IPv4 in the screenshot. You may need to try a different port number.
Good find. Enabling support for IPv6 can cause all sorts of problems, Roon is smart to recommend this. Likewise, Antipodes was smart to not enable IPv6 on Antipodes servers.
thx Kenny, I posted 2 screeshots. one is with my macbook as roon server - arc works perfectly i this scenario because i can set a pinhole through the firewall direct to the ipv6 address of roon. but as soon as i use antipodes as the server i cant, and arc doesnt work. so i know my network is ok and that the pinhole i make lets arc get through from the outside world to my roon server. just not when i use the antipodes server (
What do you mean by this? Please show how you did this for that laptop. The laptop is showing that Roon is connecting via IPv4, so not sure where IPv6 comes in.
This is on the Roon help site:
Roon should work with IPv6 as long as it doesn’t have any leading zeros in the quads. IPv6 address quads typically look like this 5f8d:2e75:… but it’s also fine if they look like 2ad5:7f3:… which would mean the second quad starts with a zero. It’s this issue that is causing the problems so if you see any 3 digit values in your IPv6 address then it probably won’t work. I think they are close to fixing this.
I see zeros at the beginning of your server address.
I suspect the NAT Forwarding section is where you would need to go to in order to allow Roon ARC to be reached from the outside without using IPv6. Can you share a screenshot of that page?
“NAT Forwarding creates open connections, aka ports, allowing devices connected to the internet to initiate communication with your local devices.” This is exactly what Roon ARC requires.
arc connects perfectly when i use a mac as my roon server so its not this format issue. i have read and tried everything suggested on all the forums - the issue is now squarely down to the oladra
nat forwarding and upnp dont work with arc and starlink, thats why you have to use ipv6, i have tried all the combinations, the only thing that works is the firewall pinhole using 6 with roon server on my mac - but not on oladra (
heres the screenshots but no matter how you configure either or both arc wont connect
After some reading, seems you are correct about needing IPv6 to enable this.
With Starlink having such slow upload speeds, I can’t imagine that the Roon ARC experience will be that good. Have you been able to try to remotely access music from Roon running on your laptop?
