Which field of the Packet Monitor shows the firewall interface for captured packets?

The field in the Packet Monitor that indicates the firewall interface for captured packets is the Egress field. This field is crucial for understanding the flow of traffic through the firewall. Egress refers to the interface through which packets are sent out of the firewall, helping administrators track outbound traffic and understand which interface the data left from.

When analyzing packet flows, knowing the egress interface is vital because it can help diagnose issues related to how traffic exits the network. This assists in troubleshooting connectivity problems, ensuring that the packets traverse the appropriate paths based on routing configurations, and verifying that the firewall policies are functioning as intended.

In contrast, other fields like Ingress refer to the interface through which packets enter the firewall, while Source Interface and Destination Interface provide details on the interfaces relating to where the packets originated from and where they are directed, respectively. Understanding these distinctions is important for a comprehensive grasp of traffic monitoring and analysis on SonicWall firewalls.
