In current development status it is only possible to have one IPv6 per interface in tracking mode. If there are more than one WAN-connections with dynamic IPv6 connection this makes the dynamic NTP feature #4881 a litte complicated because every WAN connection needs to be assigned to another interface (which is not used for anything else) and npt must then track these interfaces. The LAN-interface must be statically configured to a private IP. It would be more intuitive if the LAN-interface could have more than one IPv6: the primary could be the private IPv6 address and the second and third one the delegated adresses of WAN1 and WAN2 and NTP could track the last two addresses.

The RA-service also would need a field to select which address to announce.
