Set squid to be anonymous

This guide describes a step by step method to install a SQUID 3 server as an anonymous proxy. An anonymous proxy is a tool that comes to Internet activity undetectable. Internet access for the user, the protection of personal data, hiding the credentials of the source computer. Simply say to hide your IP address.

The post How to adopt a CentOS 5 operating system, but can be applied to CentOS 4, Fedora 5-9 with same steps andSQUID version 3. By default, Squid uses only the default IP address to communicate on the Internet, but use all available IP addresses on the server to act as an anonymous proxy, for example, if a user connects to IP1 of server then IP1 will act as a lawyer and before the same IP address, if a user connects to IP2 IP2, then act as a proxy and foward the same IP addressand so on, but will apply to user authentication based on NCSA to protect server against unauthorized use.
