Running squid.. Currently if a someone tries to use the proxy they are prompted for a user and pass which authenticates to let them surf through. I want to also let a select few subnets pass through without having to authenticate. This is the config I have now.. Have I done something wrong.. acl USAI.NET proxy_auth REQUIRED http_access allow USAI.NET acl all src 0.0.0.0/0.0.0.0 acl mva src 65.118.154.0/24 acl mva src 67.110.140.0/23 acl mva src 216.236.240.0/20 acl mva src 12.101.196.248/29 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 http_access allow mva http_access allow manager localhost http_access deny manager http_access allow localhost http_access deny all auth_param basic realm USAI-REALM Thanx Cris
