AXE16000 Can't get ipv6 working (Frontier Fiber)

[scajjr2]

Here in SE NH we have a similar issue with Consolidated Communications/Fidium. Same type of situation - CC/F bought out Fairpoint who had bought Verizion"s VT-NH-ME landline business.

In our town CC ran all new fiber in 2021, we had a PPPoE 1st year (1Gb service, Zyxel router) but no ipv6. Last year CC migrated us over to Fidium (what their home fiber division is now), DHCP instead of PPPoE, used my Asus AX86U, still no ipv6. Upgraded to 2Gb service this year, bought an Asus ROG Rapture GT-AX6000, still no ipv6. CC/F says they hope to deploy it in 2024.

Sounds like even though Frontier says you have ipv6, you don't.

From what you say, I surmise that your main WAN Connection Type (in the WAN section of the Router GUI) is "PPPoE". If that is the case, then you should indeed set ipv6 as "Native". My main WAN Connection Type is "Automatic IP", and therefore I'm supposed to set it to passthrough. See the ASUS FAQ on the subject.

Interesting. My WAN Connection is set to "Automatic IP" and the IPv6 type is "Native" in the router. It's been working fine for months now. According to the folks on the AT&T forum, when the Residential Gateway is set to "Passthrough", the RG simply forwards on whatever public IP addresses it gets to the router. That appears to be what's happening for both IPv4 and IPv6 in my config. That does appear to be in conflict with ASUS instructions, but, in my case as they say, "If it ain't broke, don't fix it."

Zentro internet here. Exact same situation on an ax11000 pro where ip needs to be automatic and ipv6 is native for any ipv6 addresses to be assigned. Router client devices get ipv6 addresses, but access to any non-lan connections is blocked. They are also not link local addresses.

I have a GT-AXE11000 on Frontier Fiber and tried to enable IPv6, (selected Native as what worked with AT&T Fiber), and system seemed to crash. When I got someone there to reboot it, the setting was reverted to Disabled. Chatted through chat box and advice was to use the eero pro 6 they provided when we signed up, that Frontier supports dual stack I believe he mentioned. I guess I could try Passthrough like the ASUS FAQ says (for Automatic WAN)? Thank you anyone who might know, in advance.

Does your Frontier market even have IPv6 enabled? Some Frontier markets have it, some do not (mine doesn't). Now that Frontier has been bought by Verizon who knows if those markets without IPv6 will eventually have it enabled (or activated).

@bennor The person on the chat asked me if I was using the Frontier provided router, (eero Pro 6 in my case). I said "no" because I use a GT-AXE11000 and TP-Link RE815XE to provide 6 GHz to the house. He said that the eero supports IPv6 and to use it reinstall it, (the pair if I actually do so). So I suspect it is supported here (San Dimas, CA). I just don't know the correct setting. (Native seemed to crash service so maybe Passthrough. I just am not physically there to tinker/reset it)....

If you have the eero(s) somewhere you may also want to try.... I went to the eero website but beyond turning IPv6 on via a toggle I didn't find what type of service it uses, (ie Native or Passthrough). There is no gateway like here at home, just an ONT. AT&T's BGW320 clearly notes "Native"...

No Eero, I declined it during Frontier fiber install. Just a Frontier XGS-PON ONT (FOX222) to Asus RT-AX86U Pro.

If you haven't done so already, maybe dig through the FrontierFIOS subreddit to see if there are any suggestions. There are a number of IPv6 discussions over there.

Edit to add: Looking through some of those FrontierFIOS subreddit discussions on IPv6 (for example this one), looks like some are setting their router's IPv6 "Prefix Length" to /56.
