Hi Friends, I am new to Squid/Squid NT...so sorry if my question sounds stupid.. I am facing a problem configuring SquidNT 2.5... None of my Network PC's can access Net..its running on default port 3128 The config file is as follows: #---------start---------- hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? no_cache deny QUERY client_netmask 255.255.255.0 auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 acl all src 177.177.177.0-177.177.177.199 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 563 # https, snews acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow all http_reply_access allow all icp_access allow all visible_hostname GreySoft #---------end---------- I have kept most of the default parameters as in the original config file.. Only the Machine where Squid is installed is able to use Squid Proxy.. Searched net but with no result.. Thanks in Advance..
