Course 32 - Checkpoint CCSA R80 | Episode 6: Mastering NAT Types, Priority Hierarchies, and Manual Rules

About this episode

This episode covers advanced NAT design and configuration in Check Point R80, including rule priority and manual translation.

In this lesson, you’ll learn about: advanced NAT design, rule priority, and manual translation in Check Point R801. NAT Fundamentals in Check Point R80 In Check Point R80, NAT controls how private and public networks communicate 🔹 Hide NAT (Source NAT) Many internal devices → one public IP Typically uses: Gateway’s external IP 🔹 Use Cases Internet browsing Outbound traffic 🔹 Static NAT (Destination NAT) One public IP ↔ one internal server 🔹 Use Cases Hosting: Web servers Mail servers 2. NAT + Security Policy (Critical Concept)👉 NAT does NOT allow traffic by itself🔹 Required Setup Configure NAT Create Access Control Rule → Accept traffic 🔹 Smart Behavior You can reference: Internal server object ✔️ Firewall automatically understands NAT mapping3. Auto-NAT Priority HierarchyWhen multiple NAT rules overlap, priority decides🔹 Priority Order (Top → Bottom) Host Static NAT (highest priority) Host Hide NAT Range Static NAT Range Hide NAT Network Static NAT Network Hide NAT (lowest priority) 🔹 Why This Matters Ensures: Specific servers keep dedicated IPs Prevents: Conflicts with general rules 🔹 Example Server inside network with Hide NAT Server also has Static NAT 👉 Static NAT…
