Try do install 3 squid instances and on every squid.conf insert
different tcp_outgoind_address of your dsl links
Next try to balance per tcp(80) session to all squid instances:
$ipt -t nat -A squid -p tcp --dport 80 -m nth --counter 7 --every 3
--packet 0 -j DNAT --to 192.168.0.1:8080
$ipt -t nat -A squid -p tcp --dport 80 -m nth --counter 7 --every 3
--packet 1 -j DNAT --to 192.168.0.1:8081
$ipt -t nat -A squid -p tcp --dport 80 -m nth --counter 7 --every 3
--packet 2 -j DNAT --to 192.168.0.1:8082
$ipt -t nat -A PREROUTING -i eth4 -s 10.0.0.0/8 -p tcp --dport 80 -m
state --state NEW -j squid
the: "-m state --state NEW" param is important ... because you must
balance over "tcp session" not "per packet"
But with this configuration some sites will have problems to load like
https ... because source of your ip will be change from dsl 1 to dsl 2
and dsl 3

I'm already using http://www.ssi.bg/~ja, this is from Julian Anatasov right, but
my problem here, in most of the cases it needs to fully utilized the 1st lint
prior to shifting to the second link.

You can't do load balance across 4 dsl link "per packet" ....
Only per session.
If your isp is doing reverse path filtering .
Try routes patch from : http://www.ssi.bg/~ja/
And it will be working fine :)

Hi Rob,
Im sorry, I forgot to inform you that the clients are not using this
3 lines to go directly to the internet, instead the on the same
machine I install Squid proxy server, hoping that with the load
balance technique, squid can take advantage of the connection
simultaneously, so my problem actualy is the squid
to use the 3 lines simutaneously.
I haven't used it myself so I'm a bit guessing here ; you may be able
to alter locally generated packets (from Squid) using the ROUTE target
combined with the nth match in the OUTPUT chain of the mangle table so
the packets are diverted over the 3 NIC's.
Something like :
iptables -t mangle -A OUTPUT -o eth0 -m nth --counter 7 \
--every 3 --packet 0 -j ROUTE --oif eth0
iptables -t mangle -A OUTPUT -o eth0 -m nth --counter 7 \
--every 3 --packet 1 -j ROUTE --oif eth1
iptables -t mangle -A OUTPUT -o eth0 -m nth --counter 7 \
--every 3 --packet 2 -j ROUTE --oif eth2
(Where eth3 is your LAN NIC.)
Gr,
Rob

Squid proxy, Im monitoring the 4 ports via MRTG and I noticed that
before It goes to link 2, link 1 must be saturated first or link1
will stop and the request is only transfered to link 2. So it
seems
that it is not doing a load balance, my idea of load balance is
utilizing the 3 lines simultaneously.

Perhaps you can use the nth patch.
