Hi, I''m trying to use HTB for IPv6 packets. In the LARTC archive I found a thread on this issue where a solution was described. The idea is to mark a user-defined chain then use the fwmark for filtering. However my attempt wasn''t successful. I''m thinking of trying my luck with the u32 filter. This is what I did, any comment is greatly appreciated. Thank you all. tc qdisc add dev eth0 root handle 1: htb default 15 tc class add dev eth0 parent 1: classid 1:1 htb rate 100kbit ceil 100kbit tc class add dev eth0 parent 1:1 classid 1:10 htb rate 30kbit ceil 100kbit tc class add dev eth0 parent 1:1 classid 1:11 htb rate 10kbit ceil 100kbit tc class add dev eth0 parent 1:1 classid 1:12 htb rate 60kbit ceil 100kbit ip6tables -t mangle -N queue1 ip6tables -t mangle -A queue1 -j MARK --set-mark 0x10 ip6tables -t mangle -A queue1 -j ACCEPT ip6tables -t mangle -A OUTPUT -d 2001:411:1:1:2:: -j queue1 ip6tables -t mangle -N queue2 ip6tables -t mangle -A queue2 -j MARK --set-mark 0x20 ip6tables -t mangle -A queue2 -j ACCEPT ip6tables -t mangle -A OUTPUT -d 2001:411:2:1:2:: -j queue2 ip6tables -t mangle -N queue3 ip6tables -t mangle -A queue3 -j MARK --set-mark 0x30 ip6tables -t mangle -A queue3 -j ACCEPT ip6tables -t mangle -A OUTPUT -d 2001:411:3:1:2:: -j queue3 tc filter add dev eth0 protocol ipv6 parent 1:0 prio 1 handle 0x10 fw flowid 1:10 tc filter add dev eth0 protocol ipv6 parent 1:0 prio 1 handle 0x20 fw flowid 1:11 tc filter add dev eth0 protocol ipv6 parent 1:0 prio 1 handle 0x30 fw flowid 1:12 tc qdisc add dev eth0 parent 1:10 handle 20: pfifo limit 5 tc qdisc add dev eth0 parent 1:11 handle 30: pfifo limit 5 tc qdisc add dev eth0 parent 1:12 handle 40: pfifo limit 5 _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
