Thanks for the quick response. I have the following in my squid ACL it just seems a bit strange that I am only letting in local traffic and external traffic is getting in. I am using dansguardian as a content filter. acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 http_access allow manager http_access allow localhost http_access deny all Kind Regards William -----Original Message----- From: Henrik Nordstrom [mailto:henrik@xxxxxxxxxxxxxxxxxxx] Sent: 14 September 2006 08:10 To: William Bohannan Cc: squid-users@xxxxxxxxxxxxxxx Subject: Re: blocking external users on a bridge whenfirewall is disabled ons 2006-09-13 klockan 19:39 +0000 skrev William Bohannan: > goes overtime on caching and external users start using it?

The default squid.conf shipped with Squid reads: # TAG: http_access # Allowing or Denying access based on defined access lists [...] # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # Example rule allowing access from your local networks. Adapt # to list your (internal) IP networks from where browsing should # be allowed #acl our_networks src 192.168.1.0/24 192.168.2.0/24 #http_access allow our_networks # And finally deny all other access to this proxy http_access deny all Regards Henrik
