Subject: Matching MLD with ip6tables
Date: Fri, 1 May 2015 04:56:12 +0200 [thread overview]
Message-ID: <20150501025612.GB2465@odroid> (raw)
Hi,
According to RFC4890 ("Recommendations for Filtering ICMPv6
Messages in Firewalls"), page 35, a rule like this should match
MLD packets:
$ ip6tables -A icmpv6-filter -p icmpv6 --icmpv6-type {130,131,132,143} ...
However, this does not seem to work for me. My guess is that it
does not match because --protocol is not 'icmpv6' but actually
the hop-by-hop-option first. Is this a bug in the RFC (and if so,
should I report it on some IETF mailing list?)?
Also, is there a way to somehow match IPv6 protocols with IPv6
options in between?
Cheers, Linus
