Hello,
Did chitambira's post work like you wanted?
I haven't used Squid in a while, but it feels as with this ACL configuration:
Code:
http_access deny sites
http_access allow mynetwork timeon
http_access deny all
It would deny whatever you put in the ACL "sites" no matter what and only allow access from your network in "mynetwork" only at "timeon"
I think that fixing the ACL definitions as chitambira pointed out and then using this configuration would get the desired result:
Code:
http_access deny sites timeon
http_access allow mynetwork
http_access deny all
Hope it works. Make sure to tell us if it works out.
Good luck
