Hiding squid

[Jamie Orzechowski <admin@xxxxxxxxxx>]

I am running squid stable 13 on a ubuntu linux box in transparent mode.  
Is there a way to hide the proxy so it will pass the test located at

http://www.lagado.com/proxy-test

my iptables rule looks like

/sbin/iptables -t nat -A PREROUTING -i bond0.998 -p tcp --dport 80 -j 
REDIRECT --to-port 3128
