Thank you for this tutorial. I'm trying to learn how to setup a mail server. And, it's not so easy, coming from a Windows background. But, I'm trying to get into Linux and learn. So, this simple tutorial about iptables is very helpful for me to build up the basic knowledge. Again, thank you. You are a very good teacher.

I searched the Internet a lot for such a tutorial. This is the best online computer networking tutorial I think. Please continue!!! You could tell us something about Protocols eg (in general and some important Protocols in detail)

Your channel is so damn good man, really easy to learn and understand. I don't have the words to express it anymore. You should have like a million subs, probably the best teacher about computers here on YouTube :]
