Thank you Andy, really I have figure out this issue.....go ahead I forgotten include my CONNMARK RESTORE rule at the last message.... so follow my whole script. there are two PREROUTING rule for new connections that they should do the load-balance but I wonder when the socond rule CONNMARK2 coming use it ?? I think never because data flows always going to into at the first rule ( CONNMARK1 ). so the second rule never is using! I think the statistc module could do that rotate at the use rules...but doesn't work! eth1: LAN Interface eth0: WAN1 eth2: WAN2 #!/bin/bash # flush all iptables entries iptables -t filter -F iptables -t filter -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X iptables -t filter -P INPUT ACCEPT iptables -t filter -P OUTPUT ACCEPT iptables -t filter -P FORWARD ACCEPT iptables -t mangle -N CONNMARK1 iptables -t mangle -A CONNMARK1 -j MARK --set-mark 1 iptables -t mangle -A CONNMARK1 -j CONNMARK --save-mark iptables -t mangle -N CONNMARK2 iptables -t mangle -A CONNMARK2 -j MARK --set-mark 2 iptables -t mangle -A CONNMARK2 -j CONNMARK --save-mark iptables -t mangle -N RESTOREMARK iptables -t mangle -A RESTOREMARK -j CONNMARK --restore-mark iptables -t nat -N SNAT1 iptables -t nat -A SNAT1 -j SNAT --to-source 192.168.217.254 iptables -t nat -N SNAT2 iptables -t nat -A SNAT2 -j SNAT --to-source 192.168.216.254 iptables -t mangle -A PREROUTING -i eth1 -s 0/0 -d 0/0 -m state --state ESTABLISHED,RELATED -j RESTOREMARK iptables -t mangle -A PREROUTING -p tcp -m state --state NEW -m statistic --mode nth --every 2 --packet 0 -j CONNMARK1 iptables -t mangle -A PREROUTING -p tcp -m state --state NEW -m statistic --mode nth --every 2 --packet 1 -j CONNMARK2 iptables -t nat -A POSTROUTING -o eth2 -j SNAT1 iptables -t nat -A POSTROUTING -o eth0 -j SNAT2 ip route add 192.168.217.0 via 192.168.217.1 table oitelecom ip route add 192.168.216.0 via 192.168.216.1 table gvttelecom ip route add default via 192.168.217.1 table oitelecom ip route add default via 192.168.216.1 table gvttelecom ip rule del from 192.168.217.254 table oitelecom ip rule add from 192.168.217.254 table oitelecom ip rule del fwmark 1 table oitelecom ip rule del fwmark 2 table gvttelecom ip rule add fwmark 1 table oitelecom ip rule add fwmark 2 table gvttelecom ip route flush cache thanks....any tips is welcome.
