Robbie suspects that a firewall with incorrect settings is preventing some systems in his network from sending traffic to his web server. He is aware that the traffic should arrive as HTTPS to his web server and desires to verify that the traffic is being received. Which tool can he employ to test his hypothesis?

Wireshark is a tool used for capturing and analyzing network protocols, making it useful for troubleshooting in situations like this. In fact, security professionals are frequently tasked with validating that traffic is being received correctly as part of firewall rule debugging. Robbie may consider capturing traffic at both ends of the communication to ensure that clients are sending traffic correctly and then compare it to the same traffic being received or missing at the other end. Although tracert and traceroute are helpful in verifying the path that traffic takes, they cannot determine whether HTTPS packets are being blocked.
