Comcast turned on ipv6 here recently and I just happened to look at my logs and I see this. What does it mean? Running 2.1.1.

Can't really tell you what it means. But, I can tell you how to clear it up.

Shutdown pfSense and power off the cable modem.
Power on the CM and wait until it syncs.
Boot up pfSense.

The errors will be gone.
