@mentalinc @taubin doing that will result in a broken IPv6 configuration. Please run "delete interfaces ethernet eth0 ipv6" then commit and save. Your /etc/radvd.conf file won't be there but I'll do some investigation and post.

I did fix it with my own router and there is no IPv6 based configuration directly under the ethernet interfaces. Long story short it is a bug in "vyatta_gen_radvd.pl" in /opt/vyatta/sbin that is causing a bailout if an older IPv6 prefix is not set however this breaks DHCPv6-PD if you set this (hence why your IPv6 won't be working) - this bug has existed forever and is yet to be fully fixed...

Worked with a restart on the HG659 -- I've noticed no problems this evening.

Will you turn on IPv6 for cache.google.com?

I see google.com goes through to Sydney on v6 vs BigPipe for v4

Seamless on the Fritz!box, clicked reconnect and came straight back up with IPv6

Same experience :)

Had enough of Edgerouters right now - no more Edgerouter related questions for the next day please. (also ping @mentalinc @taubin)

Finally got IPv6 over PPPoE working. First remove your old crap:
delete interface eth0 pppoe 0 dhcpv6-pd
delete interface eth0 pppoe 0 ipv6
delete interface eth1 ipv6

And then commit then save. Reboot the router because this bug is bloody annoying and I've found it'll more than likely not generate a /etc/radvd.conf file until you do so. Ensure you've removed all IPv6 related configuration - seriously!

Next, set up IPv6:
edit interfaces ethernet eth0 pppoe 0 dhcpv6-pd pd 0
set prefix-length /60
set interface eth1 host-address ::1
set interface eth1 prefix-id :0
set interface eth1 service slaac
top
set interfaces ethernet eth0 pppoe 0 ipv6 enable
commit

Then set a route:
set protocols static interface-route6 ::/0 next-hop-interface pppoe0
commit
save

Now reboot. Verify that /etc/radvd.conf is there and there are contents in the file. If it has generated then well done. You can verify your connection by running "show interfaces" which should show your new found IPv6.

----
(kept here for amusement since this is rather embarrassing for myself - this will teach me for staying up late doing this).

Note - there is still a chance this doesn't work. I managed to get it going once on my friends connection right up until a reboot. I've posted a bug report on the Ubiquiti forums Here for those interested. Am going to wait until I have physical access to the Edgerouter and do a full reconfiguration this weekend however I have verified that this configuration works but the Edgerouter is hella buggy with PPPoE and IPv6. There is evidence at https://img.murfy.nz/MFLAx showing that some devices still have IPv6 global addresses from the time I had it working along with me giving up for now on this router :)

Edit: Solved once I noted I had a mysterious dhcpv6-pd rapid-commit enable on the wrong interface. Now working on my PPPoE Edgerouter successfully. Renamed the thread on the Ubiquiti forums to "late night pebcak", time to sleep...

I'm going to try out IPoE on pfSense today.

I still have no clear answer on why PPPoE isn't working, but I haven't been able to put much time in to testing. The workarounds people have posted, and the fact that I got an IP one time, suggest there may be an issue with the order or timing of commands. Given Bigpipe was seeing no requests from my connection, such an issue would more likely be internal to pfSense, rather than being due to the exchange between client and server, although forum posts suggest slightly different requests are being sent from FreeBSD than Linux.

While I didn't bookmark the page (that was silly), one person did suggest an issue with VLANs and the em driver. I'd be surprised if that was the case given em is probably the most reliable of all NIC drivers, but it's worth asking to see if there is any commonality between our configurations. @OmniouS and @lucky015 (or anyone else using pfSense), are using a VLAN configuration, or the em driver?

Would you look at that shiny new IPV6 badge, Thank you so much @michaelmurfy you are amazing!

Edit, it dropped after a few minutes. A few reboots later, it's still gone. I'll give up on it for now.

I was raging, could see the IPv6 addresses in ERL, nothing on my PC would work

did ipconfig /release

ipconfig /renew

Nothing!

reboot PC and bingo we have IPV6 and the IPv6 badge to go with it!

Thanks so much @michaelmurfy!

Seems we were missing a default route and enabling the interfaces (so obvious once we see the answer!)

Also make sure you put the firewall rules back in (https://murfy.nz/files/er_v6.txt)

Hmm putting the firewall rules in broke the setup.

looks like entering configure again breaks something!

So it works but very flaky!

On a different router, but the general rules for IPv6 (my outbound is open):

- allow inbound udp port 546 (DHCPv6) on wan interface

- allow inbound icmpv6 on wan interface

- allow inbound udp port 547 (DHCPv6) on lan interface (if you run DHCPv6 server on the router)

- allow through icmpv6

That's good. I was pinging Google before as well and noticed a 10x increase in ping times. I did some further reading and found some explanation here.

Got the EdgeRouter working with IPoE and PPPoE, sadly if I reboot the router that is the end and radvd.conf doesn't get populated

Fingers crossed I don't have to reboot for awhile...
