Hello, I'm running the 374.40 firmware on an RT-AC66U. Just recently Comcast activated IPV6 in my area, at which point I started seeing the following messages every 30 minutes. This was not happening prior to IPV6 enablement and I have power-cycled both the modem and the router. IPV6 seems to be working fine otherwise:
