2.0-Release How to Quiet ipv6 multicast in firewall log.
Running 2.0-Release. Not using any of the ipv6 devel stuff.
I'm getting a ton of the following every few minutes:
Sep 23 14:35:09 LAN fe80::21e:52ff:fef6:50af ff02::1 ICMP6
Sep 23 14:35:08 LAN fe80::e2b9:a5ff:fe9f:ad84 ff02::2 ICMP6
Sep 23 14:35:05 LAN fe80::3935:c45a:9fee:b36a:53807 ff02::c:1900
I understand ff02:: being local link multi-cast (assuming I've done my homework correctly)..
I've tried every way I can think of, How can I generate a firewall rule to silently drop/block these?
They are filling my firewall log and making it difficult to find look at entries I care about.
It would seem the gui is not capable of handing ipv6 addresses, Is there another way to add
a rule to handle this?
And sorry if this belongs in the ipv6 forum, I figure this is a firewall issue, and the ipv6 forum
is geared towards the work being done on 2.1-Devel ?
(oh, I am using the Allow IPv6 / IPv6 over IPv4 Tunneling option.. I imagine turning that off would
quiet things, but not what I am looking for)
Hmmm You could bump to the ipv6 dev and then you could do ipv6 rules to not log it on block, you could completely disable ipv6 on your pfsense box so that it does not have link local address, that might work.
You could just disable the multicast at the source if your not using it
You could turn on igmp snooping on a smart switch to block it.
