Ahh, OK - I understood that incorrectly. Not sure what the issue is between your sytem and mine then.

I've done lots of reading regarding PPPoE and IPv6 and challenges are known. They are exacerbated by firewall rules that drop ICMP messages - since IPv6 routers are not allowed to defrag packets (if I have read that correctly), so send back an ICMP packet too big, which some intermediatories drop.

A common thread that I've also read, especially if your "data center" has multiple inbound paths (ECMP) is the ICMP packet comes back via a different path and isnt matched to the source, so is dropped.

Anyway, IPv4 works, so we can stick with that I guess.
