how to extract network packet information from message received from mqtt broker

[akhan839]

Hi,
My ESP32 is subscribing to the HiveMQ MQTT Broker. I intend to extract network packet information from the received packets originating from the broker. To be precise, I am interested in obtaining the following details:

IP address and port of the received packet.
Transport layer protocols of the flow connections.
Dynamically detected protocols, such as DNS, HTTP, and SSL.
Total length of the IP header field in the received packet.
I am not interested in analyzing this information using Wireshark. Instead, I aim to extract and process this information in real-time on the ESP32.

I would greatly appreciate your assistance in this matter.
