Enable Do not wait for a RA and then I'm not quite sure if I'm setting up the DHCPv6 ranges correctly. However, I can't figure out what I should put in pfSense as the Prefix Delegation. now configure pfsense to get public address by dhcp, and set private address. It is not possible to run both a DHCP server and a DHCP Relay at the same time. If I use a FritzBox instead of the pfSense, the public IPv6 address is provided via DHCPv6 to the FritzBox router, so the modem seems to do what it is supposed to do.

The DHCPv6 daemon can only run and be configured on interfaces with a Static IP address, so if a tab for an interface is not present, check that it is enabled and set with a Static IP. Anyways, this bug is particularly "beautiful": When setting up multiple DHCPv6 WAN Interfaces (so pfSense as Client that is) the config in /var/etc/dhcp6c. Your ISP apparently used prefix delegation, which is very proper, and with a /56 assignment you can create up to 256 local networks with real, public IPv6 addresses. This worked. But pfSense did not go through to the next phase of acquiring a IPv6 address lease. ULA will not work internally since ipv4 will be used before ULA. IPv6 static IP is set on the interface.
