@David-TP Yeah, I saw that thread, but as soon as I enable IPv6 the error pops up and all settings after that are not saved. I've ordered an X50 and see if that works better.

The solution: I received a special firmware from support, that resolved the issue, so it's probably fixed in the next firmware update for everyone.

Hi, I've switched provider today and I'm now using PPPoE on VLAN 6 (default KPN fiber settings in The Netherlands). IPv4 went smooth and works awesome. IPv6 gives an instant error as soon as I enable...

@JPR99 sorry i have offended you. I apologise.

for the isp side you can. For the dhcp server I don't know, but it might work. But since ipv4 nameserver will respond with ipv6 addresses, I never tried and wanted maximum compatibility for all...
