Re: [IPv6] Seeing two different LAN side ranges

Interfaces: WAN, DHCP6 client configuration:

Set DHCPv6 Prefix Delegation size to None.

Verify your WAN IPv6 address is now /128.

Incorrect. The WAN IP address is a single address (hence usage /128) but it is a in a /64 subnet. (How the heck is it going to reach the gateway if it's in a /128 subnet).

The DHCP delegation size (on WAN int) needs to be set to /64 if he wants PD on his LAN.
