In our journey through the Palo Alto Networks Next-Generation Firewall, we&rsquo;ve explored everything from basic setup to advanced policy enforcement and content inspection. But what happens if your single, powerful firewall decides to take an unexpected coffee break? That&rsquo;s where High Availability (HA) and redundancy come into play.</p> <p>This chapter is all about ensuring your network remains protected and accessible, even if a hardware component or an entire firewall fails. We&rsquo;ll dive deep into the concepts of HA, explore the different modes offered by Palo Alto Networks, and then walk through a practical, step-by-step configuration of an Active/Passive HA pair. By the end, you&rsquo;ll not only understand <em>how</em> HA works but also be able to implement it, building a truly resilient security posture.</p>
