Hi guys,

I'm stumped with a bizarre issue with IPv6 through my EdgeRouter. Once connected, IPv6 begins working for approximately 1 to 2 minutes, and then just dies out, nothing showing in logs etc. Unit itself also loses IPv6 connectivity to the internet, not just PCs behind it.

I've dumped a copy of the configuration I'm currently using here: https://pastebin.com/N602wQC1

I have also tried setting eth0s MTU to 1508, so PPPoE can operate at 1500, however that didn't appear to change anything.

Be great to get this sorted, hopefully someone else has had the same issue, and resolved it!

Cheers

*EDIT*

Output from dhcp6c.log from interface connect, through to when IPv6 stops working:

v6 appears to malfunction as the failures to remove addresses begin.
