Hello and good day!

If I am monitoring traffic on my firewall interface connected to the ISP, does traffic IN refer to traffic that goes into the ISP router from my firewall and traffic OUT to traffic going out of ISP router towards my firewall? Please advise. Will appreciate your immediate response. Thanks!

It depents, where are you monitoring. I think you do not have access to the ISP router using SMTP and you are reading the properties from your firewall network card, which is connected to your ISP Router. Then "IN" is normally incoming traffic from the intenet to your firewall

If you read the statistics from your switch port, where the firwall is connected, then IN is normally the direction from the Firwa to your Switch on its way to the ISP Router.

Tip: geht the counters and start a larger download and see, which is increasing
