If only every guide on the internet was this clearly explained, maybe the world would actually have helpdesks that understand what they're doing.
Thanks man.

What an incredibly in depth explanation of IPTables and configuration. Thank you!

[DevoShreds]

I came to review the iptables syntax for an upcoming exam and watched the whole lecture because you are an excellent teacher. Thanks for clarifying many questions I didn't know I had about iptables.

[theretromillennial]

Thanks for this. Very straight forward and helped me to figure out how to start using iptables!

[cobaltshadow]

Helped me so much when trying to understand this for a college assignment. Thank you so much!

[marcopenafort]

Thank you a lot! I didn't get what was this about in a hole semester and now it's completely clear because of you.

Great video explaining most of the basics, thank you. But I would have appreciated a bit of a deeper dive into the internal decision making of iptables. How does it decide what table to use. Or in what order are which chanes of which table applied. I think that would be very important additional basics that may not be necessary for simple use cases like they are shown here. But are really important for more advanced use cases later on. Maybe a follow up video?

[robertphillips]

Great explanation, thank you!
You've covered the 2 Chains that handle local ingres and egress. If love to see another video that explains the other 9 tables.

[dougmmm]

Excellent video, very clear and helpful. Well done.

[JayJay-kimi]

I needed a refresher, this was perfect thank you.

video title: iptables Complete Guide

video content: We will not be talking about the NAT Tables or the Mangle Tables. So really only 1/3 of IP Tables.

[andrewryabchenko]

It is a great explanation. Thank you so much for this video!

[dmneethling]

thanks for taking time to make this content

[Virimen]

Thanks for the clarifying video. You should make one on getting udp to work with 1 system streaming/recording with FFMPEG locally on OBS Studio to another system catching it to stream because I haven't found one that has really helped.

[TungNguyen-kfpr]

Very grate ! It is very simple to understand. Thank you!

[SilentSolution]

Thanks for your information and cooperation sir

[rezasharifi]

Thanks for the great video. Made such a terrifying concept so simple. But, I think the reason for the ping failure wasn't due to the filtering rule, but it was the DNS problem. Apparently, the DNS server is not set, and thus, it can't resolve the given URL.

I never wanted to learn IPTABLES and just hated it..but with your explanation I am back in this OS Firewall game....

[Handy-Handy]

[motolaoshin]

Was scared of Iptables until I saw this video.
