with respect to Administrator and Users's perspective in corporate setup?
Thanks in advance.
The choice depends on the situation and purpose in any setup because
they are different tools for different purposes. Squid is a Proxy and
Caching Server mainly for HTTP, HTTPs and FTP protocols while IP Tables
is used for a firewall. Squid can help you control, monitor and log
access to web (and FTP) while caching the content locally while IP
Tables can be used for building a firewall between your network and the
internet and regulate all network traffic passing through it.
If you have a medium to large network with sizable web traffic then you
must implement a proxy server to control web access and also conserve
bandwidth through caching. In addition an iptables based firewall cum
linux router can be used to regulate the entire internet traffic.
From the user point of view, Squid can offer access control and
authentication features based on user names in addition to IP and MAC
based access control, while IP Tables allows only IP and MAC based
access controls.
If you have an IP Tables based firewall you can also implement a Squid
based proxy server transparently. This will save you from the trouble of
entering proxy server settings in all the user systems. However, user
name and password based authentication will not work in this case.
