Hi all..

I have a Linux Proxy with 3 physical network cards and 3 different ISPs
on each port. This Linux do NATs from my private network and send traffic to
each ISP based on Iproute2 rules (ip rule) except for Web traffic. So,
im trying making squid to use 'tcp_outgoing_address' to forward traffic
from my private clients to
each ISP bases on src ACLs like this:

acl firstprivate src 192.168.1.0/24
acl secondprivate src 192.168.2.0/24

tcp_outgoing_address PUBLIC_IP firstprivate
tcp_outgoing_address SECOND_PUBLIC_IP secondprivate

but some strange things happen.. All traffic its going to my third ISP
not defined in squid.conf over any ACL or tcp_outgoing_address rule and
this ISP is not my default Gateway..

So, If i dont redirect all Web Traffic (80) to squid, iptables2 rules do
their job so well.. but if i use squid and redirect web traffic to it
make this strange things..

What do you think is happening?..

Thanks!
