Traffic view in the Monitor tab of the firewall GUI can display the information about the NAT policy that is in use for a traffic flow, if the Source or Destination NAT columns are included and reviewed in the detailed log view1. The Source NAT column shows the translated source IP address and port, and the Destination NAT column shows the translated destination IP address and port2. These columns can help the administrator identify which NAT policy is applied to the traffic flow based on the pre-NAT and post-NAT addresses and ports.

When managing firewalls with Panorama, configurations can be pushed from Panorama templates to managed firewalls. However, there are scenarios where specific settings need to be overridden on the local firewall level due to unique requirements or exceptions.

B. The modification will not be visible in Panorama:

When an override is made directly on the firewall, this change is not automatically reflected back in Panorama's templates or device groups. The local configuration on the firewall will take precedence over the Panorama pushed configuration for the overridden settings, but these local changes will not be visible in the Panorama interface. This means that while Panorama maintains central control and visibility over the bulk of the configuration, it does not have visibility into local overrides made directly on the firewalls.

This distinction is crucial for auditors and administrators to understand, as it impacts how configurations are managed and synchronized between Panorama and the individual firewalls. Local overrides provide flexibility but require careful management to ensure consistency and compliance with security policies.

To determine the egress interface a Palo Alto Networks firewall will use to route a specific IP address, the appropriate command is test routing fib-lookup ip 10.2.5.3 virtual-router default. This command performs a Forwarding Information Base (FIB) lookup for the specified IP address within the context of the specified virtual router, which in this case is the default virtual router. The FIB lookup process checks the routing table and the associated forwarding information to determine the next-hop and the egress interface for the given IP address. This command is instrumental for troubleshooting and verifying routing decisions made by the firewall to ensure that traffic is routed as expected through the network infrastructure.

To create an application-based Security policy rule to allow Evernote, the administrator only needs to add the Evernote application to the Security policy rule. The Evernote application is a predefined App-ID that identifies the traffic generated by the Evernote client or web interface. The Evernote application implicitly uses SSL and web browsing as dependencies, which means that the firewall automatically allows these applications when the Evernote application is allowed. Therefore, there is no need to add HTTP, SSL, or web browsing applications to the same Security policy rule. Adding these applications would broaden the scope of the rule and potentially allow unwanted traffic12. References: App-ID Overview, Create a Security Policy Rule
