Subject: ip6tables --set-mark drops/distorts link-local packets
Date: Fri, 03 Jun 2016 01:38:34 +0000 [thread overview]
Message-ID: <1464917914.16925.15.camel@gmail.com> (raw)
Hi all,
I discovered that marking IPv6 packets with ip6tables results in link-
local traffic being dropped/distorted. Specifically link-local UDP
traffic on ports 546-547 (necessary for DHCPv6) fails in this
situation. I provide a script for testing purposes:
-----------8<------------
#!/usr/bin/sh
ip6tables -t mangle -FÂ
ip6tables -t mangle -A OUTPUT -o $oif -j MARK --set-mark 3
exit 0
-----------8<------------
Is this behavior known/expected? My search didn't reveal any relevant
results on the web.
I am running Archlinux, uname -a:
"Linux a-router 4.4.11-1-lts #1 SMP Thu May 19 21:03:24 CEST 2016
x86_64 GNU/Linux"
George
