> When I try to ping an IPv6 address (like example.com’s IP 2606:2800:220:1:248:1893:25c8:1946 for example) I get the error ping: connect: Network is unreachable. Why? (answer: it’s because my ISP doesn’t support IPv6 so my computer doesn’t have a public IPv6 address) $ ssh freenas.local freenas$ ping6 2606:2800:220:1:248:1893:25c8:1946 ping6: UDP connect: No route to host Crap I should fix that. Login to web-interface, click the "IPv6 Autoconfigure" checkbox, click test, click save. freenas$ ping6 2606:2800:220:1:248:1893:25c8:1946 PING6(56=40+8+8 bytes) 2600:1700:3d40:6300:6a05:caff:fe58:a370 --> 2606:2800:220:1:248:1893:25c8:1946 16 bytes from 2606:2800:220:1:248:1893:25c8:1946, icmp_seq=0 hlim=54 time=11.408 ms Wow, IPv6 _is_ easy! :-) (AT&T is my ISP and it took a bit of screwing around over a weekend with my router a couple years ago to get IPv6 working properly on my home network. But it's been painless ever since.)

If you like tinkering and you've got the AT&T fiber service and don't use the voice/TV U-Verse stuff) you can get significantly better IPv4 and IPv6 performance not using their gateway (even if it's just in bridge mode with every service disabled). It's not officially supported and they actually 802.1x auth the modem but there are convenient scripts out there to proxy the auth packets allowing you to use your own router directly. Particularly helpful for maxing out their gig service or for drastically improving jitter at any service speed.

  Yup, this is me: https://github.com/jaysoffian/eap_proxy https://github.com/jaysoffian/eap_proxy AT&T has transitioned to issuing a combined ONT/Router, where this will no longer be possible, but apparently the newer gear doesn't have any of the performance issues of the Pace 5268AC. BTW, I was annoyed that AT&T installed the ONT on the southern wall of my home where it was baking in full sun everyday, so I relocated it myself into my network closet. You can just unplug the ONT and extend the existing fiber with an optical coupler and an SC-APC to SC-APC single-mode patch cable.

    Lol HN is amazing, this was actually the first one I got to work a few years back! Kudos for the tool - it worked wonders. Have you heard what gear they are using for the new >1G deploys? I haven't kept as up to date with ONT/GPON gear the last couple of years but I'm curious what they have that does 5 gigabit NAT.

      Sorry, dunno. I’m happy to have had 1Gbps for so long and I’m pretty close to getting it most of the time.

So despite spending thousands of dollars on time getting your router to work, ipv6 didn't work, but you didn't notice for 2 years?

  No, it's been working fine on all my Apple devices. I just hadn't configured the interface on my freenas server. And my free time isn't billable.

      Of course it is, do an extra day's work and bill your time.

My favorite IPv6 ping target is 2600::, a Sprint router. It's even shorter to type than 4.2.2.1 (or 8.8.8.8 for the youths).
