I am working on Red Hat Linux since last six months and learning it steps by steps. like configurating ftp server,NSF ,DNS and then email server. I want to learn squid server but technically before going into it what you suggest me that may I first learn to configure Linux as a router,Firewall machine or do IP masquerading on a server. Because all these things are directly or indirectly involve in squid.
So guide me because going to start squid i may understand Linux IP table ,how to add entries in it,how to delete entries ,I think you understand my point which i want to ask for guidence.
Squid Users configure their web browsers to use the Squid proxy server instead of going to the web directly. The Squid server then checks its web cache for the web information requested by the user. It will return any matching information that finds in its cache, and if not, it will go to the web to find it on behalf of the user. Once it finds the information, it will populate its cache with it and also forward it to the user's web browser.
2.Transparent Squid :Main benefit of setting transparent proxy is you do not have to setup up individual browsers to work with proxies,which is mostly used if you have your gateway as Linux System.And for configuring it you need to have knowledge of iptables.
So I would suggest you to learn iptables.Configure gateway server using iptables.Do internet sharing through iptables on that gateway server.Also learn to configure DNS server.
After this make Squid web caching proxy server and at last make Transparent Squid.
Also learn the difference between SNAT,DNAT and MASQUERADING
