I am analysing the script written in the ADSL-Bandwith-Management-HOWTO I found in www.tldp.org. It marks all the packets depending on the ports they use, for example: iptables -t mangle -A MYSHAPER-OUT -p tcp --dport 0:1024 \ -j MARK --set-mark 23 # Default for low port traffic iptables -t mangle -A MYSHAPER-OUT -p tcp --dport 20 \ -j MARK --set-mark 26 # ftp-data port, low prio But as far as I can see, the packet that matches the second rule, matches the first rule as well, so, I guess that when this packet is marked by the first rule (--set-mark 23), follows the chain, sees that it also matches the second rule and then it is marked again with the new value(--set-mark 26). I would like someone to confirm this. If all this is true, the most specific rules should be placed at the end, am I right? Regards, Saioa Arrizabalaga
