[squid-users] acl help

[Shawn]

I am having problems with my acl, I have the following set:
all 	Client Address 	10.10.1.0/0.0.0.0   allow
manager 	URL Protocol 	cache_object deny
localhost 	Client Address 	10.10.1.1/255.255.255.255 
127.0.0.1/255.255.255.255 allow

but for some reason others out side the network can use the proxy how 
do I stop this.
thanks
