Actually i gave up, i tried and tried and tried so many times, upgrading software falling back to an old version but it didn't work, that's it. i can't do work together tc with iptables and iproute2 when i mark a packet with iptables tc doesn't recognize them so it falls at the default leaf of the tc's tree what i like is to mark packets depending on their ip (the one who make a connetion into de linux (gateway) box) and port. i'll transcript my script because i really don't know what to do. p.d. so, what i like to do is just simple, i guess; everything comes from eth1 and goes to eth1 (lan users to linux box services) must be shapped by ipaddres + port (dport i guess INPUT/OUTPUT CHAIN?) and everything comes from ETH1 goes to ETH0 (Internet Access i guess PREROUTING/POSTROUTING/FORWARD chain) MUST BE SHAPPED BY PORT + IPADDRESS i have this situation on the linux server: eth0: (Out to internet) eth1: (LAN) configutarion: eth0 (network 200.123.166.72, broadcast: 200.123.166.79; (ip range: 200.123.166.73-77) eth0 ip: 200.123.166.73 eth0: gw: 200.123.166.78 eth0: netmask: 255.255.255.248 eth dns1: 200.123.166.73 eth0 dns2: 200.123.166.74 configuration: eth1 (network 172.16.0.0 broadcast: 172.16.0.255 (ip range: 172.16.0.1-254) eth1 ip: 172.16.0.1 eth1: gw: (none) eth1: netmask: 255.255.0.0 eth1: dns1: 200.123.166.73 eth1: dns2: 200.123.166.74 LINUX BOX SERVING THIS SERVICES: HTTP (PORT 80) SMTP (PORT 25) POP3 (PORT 110) SSH (PORT 22) FTP (PORT 20-21) SMB FS (PORT 136-139) IRC (PORT 6667) CONFIGURATION OF TC: tc=/sbin/tc iptables=/sbin/iptables echo "Building tc Classes" IFACE="eth0 eth1" for i in $IFACE;do $tc qdisc add dev $i root handle 1: htb default 10 $tc class add dev $i parent 1: classid 1:1 htb rate 2048mbit $tc class add dev $i parent 1:1 classid 1:10 htb rate 10kbit ceil 128kbit quantum 1514 $tc class add dev $i parent 1:1 classid 1:20 htb rate 10kbit ceil 256kbit quantum 1514 $tc class add dev $i parent 1:1 classid 1:30 htb rate 10kbit ceil 512kbit quantum 1514 $tc class add dev $i parent 1:1 classid 1:40 htb rate 10kbit ceil 1024bit quantum 1514 $tc class add dev $i parent 1:1 classid 1:50 htb rate 10kbit ceil 2048bit quantum 1514 $tc class add dev $i parent 1:1 classid 1:60 htb rate 10kbit ceil 256kbit quantum 1514 # USED FOR HTTP/IRC $tc class add dev $i parent 1:1 classid 1:70 htb rate 10kbit ceil 128kbit quantum 1514 # USED FOR EMAIL (SMTP/POP3) $tc qdisc add dev $i parent 1:10 handle 10: sfq perturb 10 $tc qdisc add dev $i parent 1:20 handle 20: sfq perturb 10 $tc qdisc add dev $i parent 1:30 handle 30: sfq perturb 10 $tc qdisc add dev $i parent 1:40 handle 40: sfq perturb 10 $tc qdisc add dev $i parent 1:50 handle 50: sfq perturb 10 $tc qdisc add dev $i parent 1:60 handle 60: sfq perturb 10 $tc qdisc add dev $i parent 1:70 handle 70: sfq perturb 10 $tc filter add dev $i parent 1:0 protocol ip prio 0 handle 10 fw flowid 1:10 $tc filter add dev $i parent 1:0 protocol ip prio 0 handle 20 fw flowid 1:20 $tc filter add dev $i parent 1:0 protocol ip prio 0 handle 30 fw flowid 1:30 $tc filter add dev $i parent 1:0 protocol ip prio 0 handle 40 fw flowid 1:40 $tc filter add dev $i parent 1:0 protocol ip prio 0 handle 50 fw flowid 1:50 $tc filter add dev $i parent 1:0 protocol ip prio 0 handle 60 fw flowid 1:60 $tc filter add dev $i parent 1:0 protocol ip prio 0 handle 70 fw flowid 1:70 PORTS="80 6667 20 21" #ANY IP MUST BE SHAPPED BY THESE PORTS TO THE 1:60 LEAF for i in $PORTS;do $iptables -t mangle -A INPUT -i eth1 -s 172.16.0.0/16 -p tcp --dport $i -j MARK --set-mark 60 $iptables -t mangle -A INPUT -i eth1 -s 172.16.0.0/16 -p udp --dport $i -j MARK --set-mark 60 $iptables -t mangle -A OUTPUT -o eth1 -d 172.16.0.0/16 -p tcp --dport $i -j MARK --set-mark 60 $iptables -t mangle -A OUTPUT -o eth1 -d 172.16.0.0/16 -p udp --dport $i -j MARK --set-mark 60 $iptables -t mangle -A INPUT -i eth0 -d 200.123.166.72/30 -p tcp --dport $i -j MARK --set-mark 60 $iptables -t mangle -A INPUT -i eth0 -d 200.123.166.72/30 -p udp --dport $i -j MARK --set-mark 60 $iptables -t mangle -A OUTPUT -o eth0 -d 200.123.166.72/30 -p tcp --dport $i -j MARK --set-mark 60 $iptables -t mangle -A OUTPUT -o eth0 -d 200.123.166.72/30 -p udp --dport $i -j MARK --set-mark 60 done SOOOOOOOOOOOOOOOOOO WHAT AM I DOING WRONG, COUSE EVERY TRAFFIC COMMING OR GOING JUST FALLS ON 1:10 (DEFAULT LEAF) This is an extract from the script, so it show you the LOCAL PROCESS of information not PREROUTING PLEASE HELPPPPPPPPP ME I DON'T KNOW WHAT TO DO AND MY SYSTEM IS GOING DOWN FASTER.- MY CONFIGURATION IS: ip utility, iproute2-ss050330 tc utility, iproute2-ss050330 iptables v1.3.3 kernel: 2.6.13 patch applied for kernel and iproute and iptables (esfq + wrr) heeeeeeeeeeeeeeeelp thank you so much Guillermo from Argentina
