Iptables with 3 marks. It is possible?
Hi....
I have the following question. I am using Linux Redhat as gateway of the my network to internet. I am to making NAT and firewall. I Have 3 nics eth0 - Local network ( 130 hosts ) eth1 - Link 256 full (route default ) eth2 - Link adsl 2Mb (route to forward: p2p, ftp, pop, smtp and others heavy users) I am using cbq for to limit download and try to limit uploads. In my iptables script, I need make 3 MARKs for the same packet, as following # It marks the packets that will go for link ADSL by ip route / ip rule iptables -t mangle -A PREROUTING -p tcp --dport 21 -j MARK --set-mark 2000 iptables -t mangle -A PREROUTING -p tcp --dport 20 -j MARK --set-mark 2000 # It marks the packets that will be shapped ( upload with cbq ) iptables -t mangle -A PREROUTING -m mac 00:11:22:33:44:55 -j MARK --set-mark 501 .... iptables -t mangle -A PREROUTING -m mac aa:bb:cc:dd:ee:ff -j MARK --set-mark 631 ###. I have 130 hosts in my network # It marks the packages that priority has ( with 'tc prio' command) iptables -t mangle -A PREROUTING -p tcp --dport 22 -j MARK --set-mark 100 iptables -t mangle -A PREROUTING -p tcp --dport 23 -j MARK --set-mark 100 iptables -t mangle -A PREROUTING -p udp --dport 27000:27015 -j MARK --set-mark 110 But only last mark does function Have solution ??
