WAN behaviour different on reboot compared to reload

[chris42]

Hi there,

while trying to get IPv6 working (again), I figured, that after reboot, my WAN and LAN interface does not get an IPv6. I need to reload the WAN interface to trigger IPv6 for the WAN and LAN interface.

Working on 20.7.4 with following WAN configuration:
- IPv4: PPPoE
- IPv6: DHCPv6
DHCPv6 client configuration:
- Request only an IPv6 prefix: not set
- Präfixdelegationsgröße: 64
- Sende einen IPv6-Präfixhinweis: set
- IPv4-Verbindung verwenden: set
- Verwende VLAN-Priorität: Deaktiviert

Any idea what this could be? Let me know if I can provide specific logging.
