LAN Clients don't get an IPv6 Address

[Tomdarkness]

Hey,

I have pfSense connected to my ISP's Router. Both my ISP's router and the WAN port on pfSense have an IPv6 IP assigned that is within the /56 prefix. The router is running a stateless IPv6 DHCP server:

I have set my LAN interface to track the WAN interface. pfSense can ping IPv6 addresses. However, none of the clients on my LAN receive an IPv6 address.

radvd is not listed in the services in pfSense and the log states the following:

radvd 33738 no auto-selected prefix on interface em0, disabling advertisements

Anyone got any ideas how I can get my clients to receive IPv6 addresses?

Thanks,

Tom
