[Kea-users] Kea 1.6 DHCP6 configuration on Raspberry Pi 3b running Ubuntu 20.04

[russell aspinwall]

Hi

Thanks for the feedback, my router is pfsense firewall and I 
haveconfigured the LAN side Router Advertisements as
Managed -RA Flags [managed. other stateful], Prefix flags [onlink, 
router]  but the dhcp6 client get a ::/128 address
I have also configured the correct RA subnet for the interface but while 
the clients get an IPv6 address from the pool, the subnet is still wrong.

Thanks

Russell
