IPv6 WAN router advertisements?

Hi,

 

a few days ago i updated from 6.0.4 to 6.2 and now i got every 10 sec's this messages in the system log:

 

our AdvOtherConfigFlag on wan1 doesn't agree with fe80::1 our AdvManagedFlag on wan1 doesn't agree with fe80::1 our AdvOtherConfigFlag on wan2 doesn't agree with fe80::1 our AdvManagedFlag on wan2 doesn't agree with fe80::1

 

What is this message telling me?

 

Is the FG sending router advertisements to the wan interface and is reporting that it also get informations from fe80::1?

 

fe80::1 is the gateway IP on both WAN interfaces. (The provider)

 

The WAN interfaces are configured with DHCP.

 

Regards

Stefan

I found the cause of my issue. IPv6 had been enabled on my cable modem by my ISP, Spectrum. I was able to resolve the issue by going into System --> Feature Visibility and turning on IPv6. I then went into Network --> Interfaces opened up my WAN1 port settings and set IPv6 addressing mode to DHCP. I ended up having to reboot my cable modem a couple times and renewing the WAN1 IPv4 address a couple of times, but everything did stabilize out and these event messages went away.

 

Now I have a new set of log entries flooding my my WiFi events log: "Client {mac address snipped} had an IPv6 address detected (by NONE packets) ". Need to figure out if I need to do anything about those log entries.

Have it here on 7.0.2. Thought disabling IPv6 via Comcast would free up the issue. Nope.
