Hello, I think of how to priorize incoming traffic. Therefor I read different web pages and found two different meanings. On http://www.docum.org/stef.coene/qos/docs/BB/BB.html: You can do traffic shaping with the Linux kernel. It's very important that you understand that you can only shape the outgoing bandwidth. On http://www.docum.org/stef.coene/qos/docs/mail_2.html: # suppose you want to limit incoming web traffic (you are the client not the server so the _source_ port is 80) mark the packets with 1 in netfilter # the handle seems to require to have value ffff (why ???) /sbin/iptables -A PREROUTING -i eth0 -t mangle -p tcp --sport 80 -j MARK --set-mark 1 # then add the queuing discipline tc qdisc add dev eth0 handle FFFF: ingress # limit bw to 64kbit. I'm not really sure of the burst and mtu values... tc filter add dev eth0 parent ffff: protocol ip prio 50 handle 1 fw police rate 64kbit burst 2400 mtu 9k drop flowid :1 Well, does anybody know whether it is possible to limit/manage incoming traffic in this way mentioned above or not? Thanks, Georg
