I've been fiddling with LEDE on a TP-Link TL-1043NDv1 for a while now... All i can manage is get assigned a local link ipv6 address from WAN with no prefix delegation. tcpdump on WAN after pppoe connection with dhcpv6 trying to request for a prefix returns the following:

Anybody using LEDE having any luck with the configuration?

IPv6 working happily here on an Asus RT-AC68U with a couple of Android phones, couple of Win10 systems and a Synology NAS.

The Xbox One refuses to accept it, but from what I can find they use a fairly broken Teredo implementation?

Been getting a bunch of internet drop outs this afternoon.

"IPv6 Internet connection was cleared; prefix no longer valid."

Assume you guys/gals have been doing some tinkering? ;p

I posted earlier in the thread. I've managed to get LEDE working without any issues on IPv6.

I'll try post some more info later as I'm on mobile, but definitely works no problems. This is using a custom build of trunk.

We've not made any IPv6 changes recently, no. Any network changes are done during the early hours of the morning in order to reduce impact as much as possible.

If you continue to notice trouble, could you post the relevant logs from your router?

I've collected further logs from the router upon trying to request a prefix via dhcpv6. If I'm not mistaken, there appears to be a response, but my router is not capturing it for some reason.

Thanks for your reply Aaroona, are you refering to the latest snapshot of LEDE that you're using?

Thanks to Bigpipe for allowing me on their IPv6 beta at short notice.

I can confirm that I am able to connect IPv6 successfully with a Draytek Vigor 2710 Series DSL/Router:

DSL Router: Draytek Vigor 2710VDn
Firmware Version: 3.6.8.6_2471201
Build Date/Time: Dec 6 2016 17:59:56
ADSL Firmware Version: 2471201_A Hardware: Annex A

In the router web admin interface there wasn't a need to change adsl connection settings for PPPoA, despite recommendation for the IPv6 internet settings that the IPv4 WAN setting should be PPPoE client when choosing the IPv6 connection method to be PPP (choosing DHCPv6 didn't work), please see attached screen shots.

Needed to disable generic IPv6 ICMP packet filtering to allow packet fragmentation to resolve properly.

Check the main IPv6 button displayed on the top left of the web admin pages is in its default "green" state (ie ON).

There isn't great flexibility in the web admin interface for manipulating IPv6 features or PPPoE for that matter, but while not documented the full range of ip6 commands are available via telnet to the router.

These ip6 telnet commands are documented for the 2860 series, use that as a guide for further experimentation:

Has there been any changes over the last couple of days? I've just noticed that my Office 365 connectivity has dropped from my Windows 10 PC. It only starts to work again when I disable IPv6 on my machine.

Unfortunately don't have another Win10 machine to test with at the moment, but thought I'd throw it out there in case anyone else has had the same issue.

EDIT: was definitely the connection.
Rebooted a few more times (router) and it finally came right. Not quite sure what was wrong, but IPv6 connectivity seems to be back.
Weirdly IPv6 addressing was working fine before, including after a reboot, but no traffic was being passed (which is why when disabling IPv6 it allowed IPv4 through).

Will do some more monitoring and see if it happens again. Had I had more time this morning, I would have been sifting through logs...

Nope, no changes have been made to our IPv6 implementation recently.

Quick problem to report with IPv6, although I don't know whether it's down to Bigpipe or a firmware bug in my router (NetComm NF4V):

My VDSL connection has been retraining overnight a few times recently (now approx 70Mbps downstream - blimey!), and when it comes back there's no IPv6. Restarting the router or manually disconnecting and reconnecting WAN service through the router's web configuration resolves the problem.

hi @treblE87 -

At the moment I'm using LEDE Reboot SNAPSHOT r3674+3-2261c9c running on Kernel 4.4.52.

I'll be re-compiling using the latest snapshot very shortly, but I've had IPv6 running fine the last few builds.
I am "custom" building my firmware for a wndr3700, but as far as IPv6 connectivity goes, it is only using the standard packages available in the LEDE repositories.

If it's any help, here is a dump on my currently installed packages: https://pastebin.com/je3hx4Wv

I have noticed a couple of hiccups with losing IPv6 connectivity over the last week though - even after a reboot it sometimes doesn't come back straight away. Going to have a read through the logs today and see if there's anything obvious causing an issue.

Thanks Aaroona,

I've tried the 24th of May snapshot, but it wasn't stable enough to boot on the router. I'll try again with the latest snapshot.

Great - if you are compiling your own firmware from the snapshot, make sure you tick the "Enable IPv6 support in packages" option under General.

I can't remember if the generic snapshot has it enabled, but I'd be surprised if it didn't.

Mine is currently compiling, but I'm using a new buildroot, so will take an hour or 2 to complete.

Okay interestingly, the latest snapshot is definitely having some issue with IPv6. Not sure why - its definitely getting delegation and assigning IP's to clients. Going to tinker a bit tonight, hopefully.

Well I have spent a couple of hours on this and have narrowed it down to the 'network' file stored in /etc/config
Going to post on the LEDE forum now to see if I can get some pointers, as I've about done all the troubleshooting I can think of and may have some tunnel vision.

Basically, if I generate a new ula_prefix it seems to work fine. (or if I use my original one from my backed up 'network' file before I started tinkering).
to generate a new prefix, I went here: https://www.ultratools.com/tools/rangeGeneratorResult?globalId=&subnetId=

Really not sure what is causing it and why the out of box prefix is not working (as it generates a new prefix after every factory reset) - Something very, very strange that I've not seen before. Doesn't help that I'm not too skilled with IPv6 yet... still learning!

@treblE87 - try generating a new ula_prefix, enter it into the 'network' file, or via LUCI under 'Network' > 'Interfaces' > Global network options, then do a reboot of the router.
