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 -F 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 -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
