Gain an understanding of the network connection and flow that takes place between hosts; how stateful and stateless firewalls block or allow traffic based on rules; and how the Linux system uses Netfilter, IPTables, UFW, and Firewalld for packet filtering. Learn how to open and close service ports on Ubuntu and CentOS, how to configure a Linux system to function as a NAT router, and how to define the services and ports used to manage a Linux system.
