Hi all,

I'm not sure when, approx a month ago, IPv6 stopped working for me on Quic. It mostly isn't a problem since things tend to automatically fail back to IPv4 - but a bunch of my Debian VMs are playing up (unless I dsiable IPv6 on them) - which is what made me realise there is a problem. Looking at trace route (I've anonymised my IPv6) the traffic seems to stop as 2407:8b00:10:10::ee which appears to be a Vetta IP.

Tracing route to one.one.one.one [2606:4700:4700::1001]
over a maximum of 30 hops:

1 1 ms 1 ms 1 ms pfSense.lan [2407:8b00:aaaa:bbbb:cccc:dddd:eeee:ffff]
2 14 ms 12 ms 12 ms 2407:8b00:10:10::ee
3 * * * Request timed out.
4 * * * Request timed out.
5 * * * Request timed out.
6 * * * Request timed out.

Are others having the same problem? @quic any ideas?

Could this user's problem be related? Packet Loss - Wife unhappy - trademe slow

Regards,

Luke

Works for me (I could provide a traceroute but it looks very similar to the one above by Pete). At this stage I would assume something isn't quite right at your end and disclose some more info so that you can gain some feedback. e.g. do you have a static allocation? have you got recent logs to show you have requested the address range? (has it expired or changed). My DHCP v6 client seems to be renewing the ipv6 prefix (IA_PD) about every 30 seconds

Funny you say this. Couldn’t tell if it was related to some network work I did but I lost V6. Had to drop the PPPoE session and re-establish it and all came right magically.

I applied the settings to the WAN interface again (which I guess restarted PPPoE), and IPv6 seems to be back. The weird thing is, I'm sure I had rebooted and that should have had the same effect.
