A Deep Dive into Troubleshooting

In this chapter, we will learn how a session is formed and how flows traverse the firewall. We will learn how to interpret global counters and take things a step further to look at all the stages that a packet goes through between entering and leaving the firewall. We will see how sessions are set up and how packets are handled at every step.

In this chapter, we’re going to cover the following main topics:

Understanding global counters
Analyzing session flows
Debugging processes
CLI troubleshooting commands cheat sheet

By the end of this chapter, you’ll be able to analyze all the phases a packet and a session go through while traversing the firewall, and figure out what might be going wrong.
