Packet Flow and Expected Traffic

Easy Explanation of Traffic Behavior

Now that you have learned about physical In/Out-Interfaces on the packet flow diagram and the determining roles of the traffic direction, it is time to discuss the three main types of expected network traffic, namely In, Out & Forward, and how to monitor them in RouterOS.


Our latest video talks about this issue so without further ado, take a look below:

Here's the Gist

In this video, we discuss the behavior of three types of network traffic: 1. Input, 2. Output, and 3. Forward.


After a brief reminder of the Local Area and Wide Area Networks from the viewpoint of the Class AP on our MTCNA home lab, we take turns talking about each of there traffic types, discussing their main characteristics and how they behave on a simple network.


Afterward, we talk about firewall filter rules and how they, together with logging, can help you monitor these traffic variations as they travel through your network.


We also touch upon the use cases of setting up firewall configurations on each of these traffic types, a topic that will be discussed in more and more details as we move down the road.

We've Just Started Module 3...

If you're behind on our tutorials, we have just started the third module of our Online MTCNA Program. We're dealing with the main subject of firewall as Module 3 since it will pop up repeatedly in subjects such as bridging, routing, wireless and so on.

The good news is that we're not that far along yet, and you can catch up by watching the video below as well that deals with the topic of physical interfaces on the packet flow diagram.
