IPv6 with Sonic ONT

[graeme_stewart]

Absolute nonsense, both an IPv6 and an IPv4 address should be returned concurrently if requested by the upstream router. Sonic appears to have a broken IPv6 implementation at the moment.

Just chatted with support trying to get IPv6 to work on my pfsense setup. I got a surprising response:

Your router would be configured to grab an IPV6 address, or an IPV4 address. Our system is designed to provide your device with either, depending on what it is requesting. It all depends on how your router is configured.

When I asked to clarify:

As mentioned above, our equipment is designed to provide your equipment with what it is requesting. We can't provide your router with two IP addresses. It will grab an IPV4 or IPV6 address, depending on which is enabled on your device.

And for the record, I had this working when I was on Xfinity so I know it's not the router's fault.

I'm sorry for the misinformation from our tech support representative. You can have both a IPv4 address and IPv6 address at the same time. I confirmed that IPv6 is deployed in your area for a /56 prefix delegation and your circuit shows an IPv6 address ready for allocation. I'm unsure of what's wrong with your router's configuration, but everything look good and ready-to-go on our end.

Kind regards,

Multiple customers have this issue (myself included) the ONT reports IPv6 as "service down", please, please can we get some technical assistance troubleshooting this?

Incorrect info aside, Sonic recently rolled out their IPv6 here in Santa Rosa. After a reboot, pfSense was able to pull a /56. Posting some screenshots in case its helpful (vlan interfaces are all set to track with assigned prefix IDs, RA, etc.).

Hi Graeme,

I'm sorry to hear that you're having trouble getting IPv6 working on your connection. I did double check your specific circuit on our end and see there's other customers on the same network card serving your neighborhood with an active /56 address on their Eero's, so IPv6 is active in your neighborhood.

We are pretty limited in how we can help with the router configuration for third party routers as we are only trained on our rental equipment. However, we can try sending you a rental Eero to test with to rule out the router config.

Kind regards,

If n is the number of customers on this card with an active /56 is n > 1? If that answer is yes, I'll keep debugging on my end.

Graeme, there's at least one customer on your pon segement with at /56 active.

That's an ambiguous answer to a yes/no question, which is odd. Maybe you're being polite and trying to suggest it's a dumb question (also ok).

Is n > 1 (not n =>1) where n is the number of IPv6 customers with an active /56 delegation?

Also, my router shows the connection to the Adtran, and it responding, but not with a globally routable v6 address:

Code: Select all

Which is consistent with the earlier Adtran showing as v6 service down.

It just means I manually thumbed through all of the active customers on your pon segment and stopped when I found someone with an active and functional /56 lease which is confirmation enough that it ought to work for you.
