Introduction to IPTables

[@suswiththehomies]

8 Years later and still relevant. Thank you for taking the time to put this together.

nano doesn't use Ctrl-S - Save because Ctrl-s halts output in most terminal programs. The display would freeze. Ctrl-S is "XOFF", while Ctrl-Q is "XON". To unfreeze the display after an XOFF, type Ctrl-Q.

[@elizabeth3280]

This was put together in a really easy to understand format. Thank you!

Last time I messed with iptables was back in 2003, I configured a Redhat Linux box with 2 NIC's as a DHCP/DNS/NAT/Firewall server. I've slept since then but I can see not much has changed. VERY helpful video. I love the presentation, keep it up!

[@def__luisAM95__]

Great explanation, thanks man!

[@scattycat7271]

You could charge folk for whats in your head, remarkably well explained, not once did i even consider distro's. i tire at explanation videos being laid out in ubuntu.

[@Mazamaru1]

[@cheviot2988]

cheers pal, this will be of much help !!

[@linkonLINKON-eq5yz]

Very well put together, and informative..However my only problem is figuring out if my ISP, or my home router will be defined as my server address

[@kallikantzaros]

So at 7:24, the attacker must be on the same intranet/LAN to do this attack, right? If not, how can he spoof victim's IP address and act on the network like that?

[@Smarkalbert]

Thank you for your videos.

[@vigneshnatarajan107]

delivered the concepts simply....... great !!!!!!!!!!!!!!!!!!!!!!!! :)

[@akmaljonsadikov]

[@GabrielGutierrez]

[@jefsomething]

Anyone knows why "--dport" does not show in "man iptables", or "iptables --help" either? Once using a DROP policy, any rules I tried (the one from that video included), I can't ssh anymore. using iptables 1.6.0 in virtualbox 5.0.24, ubuntu 16.04

[@Jialinwangcater]

Pretty awesome lecture... Helped me a lot...

[@edustest9948]

tried to use iptables to block facebook...but that is just to strong. even used that 443 port but still didn't succeed any suggestions ?

[@karimkazia]

thank you . excellent Lecture!

[@eranhober3929]

great video! much appreciated!

[@jamescurcurato5779]

whats the path for the firewallrules executable ?

[@edustest9948]

what if I want to block IP but I like to let only 1 of 12 users to have access to this IP

[@Moon-tg2so]

can i ask you one question Sir? I am stuck in between of my task and couldnt find answer of it.

[@scattycat7271]

Briliiant thanks for sharing.

[@SunHail8]

Thanks for good video. actually, deny policies ain't only more secured, it's more compact/fast/(lite for cpu + ram) as well.

[@funwithvirat3823]

At 17:10 (icmp packet rules), second rule should have interface option as -o and not -i . Please correct me if i am wrong.

[@cheesymangooos]

[@user-PoliceMisconduct]

"iptables v1.4.21: Can't use -i with OUTPUT", had to instead -o wlpl2s0

[@problematicpunk]

Why are the subnets "/8", "/12", and "/16" instead of "/8", "/16", and "/24"

[@pazuzucrowley2768]

Computer and Network Security, ¿there's a way to debug the script and show where may have or identify an error if that would be the case?
