Somebody use my Squid Proxy server outside. How I can stop outside accessing in Squid Proxy server. I have deny all http_access. But I am not understand how can he use my Squid Proxy server outside. Thanks a lot advance.

MAnage your Acl Properly to block the unautherised access .Here are some settings in squid.conf to look into. acl lahore src 192.168.0.1/255.255.255.0 (By this I have define a class of IP’s with the name lahore . Now I will allow or deny this class in the ACL. Any class may be made in the ACL and it can be allowed or denied.) (Ports I have opened on Squid Server: The following are some ports and their description, which we have opened on Squid server for its connections to the world of Internet. SSL_ports are those which are secure and Safe_ports are those which are standard.) acl SSL_ports port 443 HTTP Protocol over TLS/SSL acl SSL ports port 563 NNTP Protocol over TLS/SSL acl Safe_ports port 80 HTTP (Normal) acl Safe_ports port 21 File Transfer Protocal acl Safe_ports port 70 Gopher acl Safe_port port 210 Wais,ANSI acl Safe_port port 1025-65535 acl Safe_ports port 280 HTTP-MGMT acl Safe_ports port 448 DDM-RFM acl Safe_ports port 591 Filemake acl Safe_ports port 777 Multiling HTTP acl CONNECT method CONNECT http_access allow lahore (The IP class with name lahore is allowed by this. ) http_access deny !Safe_ports (The connection is refused if it is not on Safe ports ) http_access deny !Safe_ports http_access deny !Safe_ports http_access deny CONNECT !SSL_ports (Connection is refused if it is not on SSL-ports) http_access deny all (It will deny all other connections to be established other than I have allowed in the above access control lists) I hope this will help you Regards Ashfaq
