Weird Network Traffic to Proxy

  • Hi Guys,

    Can someone explain what this traffic means?

    Everyday, this PC has an average of 10GB of Upload and Download from that HTTP_Proxy which is the pfSense proxy server. I think it is weird because all clients have a traffic that look like this:

    The Application protocol shows the website that the user is talking using the default port in pfSense. But the first image is talking to the pfsense. What does it mean?

    Thank you!
