Study Notes
Source NAT
- Translates private addresses to make traffic routable across the internet
- Offers different options for setting the size and nature of the translated source address pool
Source NAT Types
- Static IP: Changes the source IP address, leaving the source port unchanged
- Dynamic IP: Translates private source addresses to the next available address in the specified address range
- DIPP (Dynamic IP and Port): Multiple clients can use the same public IP address with different source port numbers
Service Routes
- Path from the interface to the service on a server is known as a service route
- Configured using Device > Setup > Services > Service Route Configuration
- Allows access to external services through an in-band port
Role-Based Profiles
- Define sets of custom privileges for administrative user accounts on the firewall
- Include four types of privileges: Web UI, XML API, Command Line, and REST API
- Role-based privileges on the Command Line tab are predefined and cannot be customized
User Authentication
- Firewall authenticates users in two scenarios: administrative access and access to network resources
Layer 3 Deployment
- Enables routing traffic between multiple Layer 3 interfaces
- Requires an IP address assignment to each Layer 3 interface
- Supports features like App-ID, Content-ID, User-ID, SSL decryption, NAT, and QoS
Interface Management Profile
- Defines the type of firewall management services accessible through the Layer 3 interface
- Protects the firewall from unauthorized access by defining permitted protocols, services, and IP addresses
Virtual Router
- Participates in Layer 3 routing to obtain routes to other subnets
- Supports dynamic routing protocols: BGPv4, OSPFv2 and v3, RIPv2, and multicast protocols PIM-SM and PIM-SSM
- Uses virtual routers to populate the IP routing information base (RIB) and forwarding information base (FIB)
Static Route Path Monitoring
- Allows the firewall to remove static route table entries when a path failure occurs upstream from the firewall
