Flood of DHCPv6 log entries…
-
Hi,
I have a pfSense 2.1 setup with a wifi and lan segment which are both IPv6 enabled, and which have both DHCP and DHCPv6 enabled.
I have noticed strange things since I installed the second IPv6 subnet. DHCP daemon dying, and in particular a continuous flood of entries in the DHCP logs:

Thanks!

No problem with that at all here. Definitely requires more information.

I'll give more detailed information next week. But it looks like it is somehow related to the Apple AirPort access point (configured in bridging mode) which is connected to our LAN.
