Configuring and Implementing Linux's iptables - Part 1

Configuring and Implementing Linux's iptables - Part 1. Part 1 covers the three P's = Packets, Protocols and Ports. Part 2 covers configuring catch-all rules in iptable's built-in chains. Part 3 covers configuring specific TCP and UDP rules. Part 4 covers configuring ICMP rules.

My CS degree at my university didn't cover networking at all.
I learned a *lot*, but nothing about networking.

This is an absolutely great introductory overview.

Really like how you started by giving a context for iptables + networking
rather than just jumping in & doing a walkthrough of the manpages.

You Make the Best Linux tutorial On YouTube! I advise anyone trying learn Linux to view your videos.

I have a solid understanding of networking, but you sir explain things in way that is easy to understand. Only one thing you could improve on is slowing the pace down a little. If I had no knowledge in networking, I'd have to so I could understand what is being said.

iv always wondered what port does ping use? im having issues tyrying to ping a virtual machine im trying to let internet users visit my virtual machine via mobile network can you make a vid on this plz for mint 17.2 and windows 10 (the linux is the virtual server via virtual box)? i have no router so i cant do hardware port forwarding but still wana be able to try and do it by using ip tables and software firewalls etc!

Very clear and concise series. It's quick for quick reference too.
Many like to over complicate. This is just right.

Any plans for going a little deeper, past the basics?

[ricosun]

nicely explained as an intro ! every nice

[raj]

Marvellous video, very deep knowledge
Carly salali, Where you leaned this deep knowledge, can you suggest something ?

[muCephei_]

Ok, I'm still a noob with iptables and learning it right now, but can you show me a simple rule I can use right now? I only use the web browser as well as the terminal for any connections. As for the terminal it's only for installing packages and not telnet, ftp or ssh. Much appreciated!

[ashu]

how to set up that client server thing ?

[dileepmeena]

i want to block my traffic on port 80 and 443. but these command of iptables can't do it. why.. ??
iptables -A OUTPUT -p tcp --source-port 80 -j DROP
iptables -A OUTPUT -p tcp --source-port 443 -j DROP

Thank you sir for sharing..i learned lot from you..pritiated

[BeachSamuraiStudios]

I find the music not distracting at all nice video mate
..thumbs-fucking-up brah

[iptelbd]

thanks
i need to know to con fig http port user pass

[kidknw]

Dude. The music. What were you thinking?

[noncreativenickname]

Would be really good if not for the poor audio quality. IT jargon is a tough stuff, nonetheless you speak very quickly, add background music, and do not eliminate the fuss. Surely a good video, but could be much better served.

[attiqahmed]

Thank you sir....little slow would be better...than the best.
