Hi Arios,

People have used and tested this.
I was trying a similar one, but was trying for round robin distribution.
But didnt quite work perfectly.
In the end I decided to use Mikrotik, which cost me 45$ [ which is fine
for the amount of time I would have wasted with iptables ]
Infact, I was partially successful using nth match. But it didnt do a
perfect round robin. Here is what I tried :
iptables -t mangle -A PREROUTING -i eth0 -m state --state NEW -m nth
--every 2 --counter 2 --packet 0 -j CONNMARK --set-mark 1
iptables -t mangle -A PREROUTING -i eth0 -m state --state NEW -m nth
--every 2 --counter 2 --packet 1 -j CONNMARK --set-mark 2
ip ro add table 10 default via 10.90.101.1 dev eth2
ip ru add fwmark 1 table 10
ip ro fl ca
ip ro add table 20 default via 10.90.102.1 dev eth3
ip ru add fwmark 2 table 20
ip ro fl ca
iptables -t nat -A POSTROUTING -o eth2 -j SNAT --to 10.90.101.2
iptables -t nat -A POSTROUTING -o eth3 -j SNAT --to 10.90.102.2
ip ro add default nexthop via 10.90.101.1 dev eth2 weight 1 nexthop via
10.90.102.1 dev eth3 weight 1
EXT IF :eth2 and eth3
Debian Sarge 3.1 - kernel -2.4.27 [ patched with patch-o-matic XX ]
All the best.

Dear,
anyone have experience bout load balancing on multiple isp ? i have 3
connection from different isp (A = 64kb , B = 128kb , C = 128kb).
howto mix these 3 isp into 1 virtually.. so if bw on ISP A is lacked
then the connection will move to ISP B. currently i did manual route
for specific network to specific ISP... it really hard to balance it
with manual route. any clue ?
