squid/diald problems

Hi,
i have installed squid in two places,in office (moloch.pandora.it)whitch has a
direct connect to the internet and it works great :)
I have installed it also at home,where i connect to the internet with my
linux box by diald.
The problem is that every 5 minutes squid make a connection to
a site sharwen.something... and cause diald to pick up connection...
Does any one have idea hot to stop it?
Best regards
