I am looking for a script that can load balance traffic outbound with tc and iptables between three different connections.
I am using nat on the internal interface eth3, and I need to send and balance out to three other connections eth0-2. I would appreciate any help anyone can give me.

The only problem is that route and random are not supported anymore in the 2.6 kernel.

Hi jon37325

instead of -j ROUTE you can MARK the packets an user policy based routing using ip:

ex.:
iptables -t mangle -A PREROUTING -i eth1 -p tcp --sport 1000 -j MARK --set-mark 5

ip route add default via 192.168.0.1 table linkB
ip rule add fwmark 5 table linkB

regards,
pC
