/sbin/ip route add 127.0.0.0/8 dev lo scope link table natips
/sbin/ip route add default via 217.10.130.1 dev eth2 table natips
/sbin/ip route flush cache
/sbin/ip rule add fwmark 66 table natips

#Put to Second line
iptables -t mangle -I PREROUTING -i eth1 -p tcp --destination-port 21
-j MARK --set-mark 66
iptables -t mangle -I PREROUTING -i eth1 -p tcp --destination-port 80
