[squid-users] tcp_outgoing_address stalls squid-2.5S2

Greets,

I'm using this normal squid installation for about a year.
Now I wanted to instruct squid to send outgoing traffic to a new interface:
eth1. This server is using eth0 for mail and other services.

So, I just added this line to squid configuration:
tcp_outgoing_address 10.10.10.8

This would mean that all squid traffic pass by eth1's ip: 10.10.10.8

But... It doesn't work! Squid stalls, and give no answer.
Log files record the request, but never contacts remote web server.

I already changed all *output and *incoming directives on squid.conf, but the
result is allways the same.

I have no clue, since running ping and traceroute commands with
interface-forcing, i get sucess.

Please check the following logs and letme know if you have any clue.

TIA

I have this route configuration:
Destination Gateway Genmask Flags Metric Ref Use Iface
6.4.18.160 0.0.0.0 255.255.255.240 U 0 0 0 eth0
10.10.10.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1

0.0.0.0 10.10.10.252 0.0.0.0 UG 0 0 0 eth1

And this IP addresses:

    inet 10.10.10.8/24 brd 10.10.10.255 scope global eth1
