[squid] pfsense 2.0 + squid : transparent mode not working

[greeeg]

Hi,

I'm finishing to build a new gateway with pfsense 2.0. All is working well. Now I want to install a squid proxy with transparent mode. So I installed squid package, check "transparent" option in squid configuration but it does not work. But if I configure a proxy in my browser… it works !

I read http://forum.pfsense.org/index.php?topic=31132.0 and some other topics but nothing helps me.
Someone can help me ?

Thanks for all!
Greg
