Using IP tables for configuring a firewall

One of the essential steps while securing a Linux system is setting up a good firewall. Most Linux distributions come pre-installed with different firewall tools. Iptables is one such default firewall of Linux distributions. For older versions of Linux kernel, Ipchains was the default firewall.

Getting ready
