Constant IPv6 "ping" from WAN to ff02::16

[dmitripr]

Hello,

I installed pfsense for the first time a few days ago. Still learning my way around.

I've checked the Firewall log a few times after install and all seemed normal. However, after running it for a day I start seeing a "flood" of IPv6 pings, every second, from WAN, with destination being ff02::16. The source address is link local: fe80::213:5fff:fe05:bde2.

What is going on here? If this is OK, is there a way to not log these specific entries?

Thanks a lot!
Dmitri

Some more info.

I enabled DHCP6 on my WAN side, then went to check the interface status. Turns out the IPv6 of fe80::213:5fff:fe05:bde2 is actually my Gateway IPv6.

Should I allow this traffic to go through from my Gateway IPv6?

Thanks!
