Iptables is a command-line tool that allows you to view, add, and remove firewall rules on a Linux system.

Iptables is a versatile tool that can be used to implement a wide range of firewall rules. It can be used to block specific IP addresses or ports, to allow only certain types of traffic, and to redirect traffic to different destinations. Iptables is also a stateful firewall, which means that it keeps track of the state of network connections and can use this information to make more informed decisions about how to handle traffic.
