IPTABLES [PART-1] : "UNDERSTANDING THE CONCEPT"

Hello Everyone! This is Part-1 of two part video on Iptables. Iptables is a firewall tool in linux system that provides an interface with the packet filtering framework of Linux Kernel known as "Netfilter". In very simple terms, it is a powerful tool to manage network packets coming to and going out of your system.
For the sake of simplicity and easy of understanding, I am going to cover this topic in 2 part. In Part-1, we will cover the basics of using Iptable and Part-2 will be about command syntax and Live demo.
In this Video we will understand 3 basic terms used in iptables. They are
1) Table
2) Chains
3) Rules

[@peterg91]

Thanks a lot, valued even in 2024 before diving myself straight to nftables to use as latest fashion in Linux firewalling.

[@rashmitrathod6873]

Hidden gem and lucky that I found it. Thanks a lot Vineet for all the efforts in covering such a gr8 detail with beautiful presentation. It indeed helps a people like me who had less experience in working and knowing Linux internals. Looking forward to more such video. Thanks again !!

[@jfelix3523]

Thank you very much. I could not figure out why I could not get iptables working and your video explained it perfectly. I was trying to use the filter table's output chain to reject packets destined for another host (in a Linux firewall). Your explanation at 5:26 was exactly what I needed. I changed it to the forward chain and now it works perfectly. Thank you so much.

[@chilloutshow]

Would you like to be my mentor ? Please guide me for career ?

[@gillt1975]

Thank you for this video. It was very useful. If I may, I understand that english isn't your first language and Kudos to you for learning and teach in it. One word distracted me to the point I had to re-watch it. "Component" We pronounce that compooooonent, a long "o". No offense intended. Great video.

[@kamalchan9756]

bro we need work on terminal to understand

[@cryp0g00n4]

OMG, iptables are so annoying - speaker was good explainer but my god, every word was important - I hate concepts where you can't take a break from the explanation
