I used WireShark on the WAN interface and I can confirm that the messages are all ping requests. Further, I can confirm that all of the addresses have been mangled. They are logged as fe80:5::, but the correct addresses are fe80::. I created a bug report.

Hi Daryl,

Can’t say I’ve seen it before, can the firewall be a bit too strict?

I read ICMP messages, but I don’t see this in the log you post. Do you have any idea what sort of ICMP messages?

Regards,

Michel
