Hi all, Apologies for this, if it's a common question. I *have* looked in the FAQ but haven't managed to resolve my problem. I'm looking to reverse host a number of sites on different servers through a singe exposed IP address. I've populated the local hosts file (Squid 2.5 for NT) And Squid itself is firing up. No matter what I put in the acl lists, I keep getting a url could not be retrieved error. I'll qualify that by saying I haven't yet put the correct config in the acl lists ;-). In the interests of getting somewhere, I have supplied the acl portion (without the majority of the commenting) to see if there is anything obvious. I haven't used the http_accelerator options, should I? To me, the proxy should function from both sides equally well, as It's only resolving requests that will match entries in the hosts file. Thanks John #Recommended minimum configuration: acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl int_net src 172.23.0.0/255.255.0.0 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 CONNECT method CONNECT # TAG: http_access #Default: #http_access deny all # #Recommended minimum configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager http_access allow int_net # Deny requests to unknown ports http_access deny !Safe_ports # Deny CONNECT to other than SSL ports http_access deny CONNECT !SSL_ports #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # Example rule allowing access from your local networks.
