Title: IPv6 multicasts flooding logs
Post by: nspritz on July 30, 2015, 02:40:56 pm

I have IPv6 disabled in the General settings, however I see a lot of blocked IPv6 (ICMP) traffic originating from the LAN and lo0 interfaces being logged.
------------------------------------------------------------------------
IF           Source                         Destination        Proto
LAN       [fe80::20d:b9ff:....]     [ff02::1]         ICMPv6
lo0        [fe80::20d:b9ff:....]     [ff02::1]         ICMPv6
------------------------------------------------------------------------

I tried to create a non-logging block rule for this traffic, however it continues to log the traffic anyway.

Does anyone know how to suppress IPv6 logging?
Thanks!

Uncheck "Log packets matched from the default block rules put in the ruleset" under "Status: System Logs: Settings".

(This setting is checked by the default installation.)

Funny thing is I just allowed lo0 traffic for IPv6 even with the disallow IPv6 option, so you won't see this anymore starting with 15.7.6 (tomorrow).
