I was learning ACLs for years. This video is the first that simplifies the usage of ACLs. Great work.

[@gaijinfishing]

Thank goodness for your style of explanation. Short and to the point. Easy to understand and digest. I've watched a lot of videos on a lot of topics and I'm finding these to be very valuable. Thank you! Working on knocking out a CCNA and then going for the CCNP and your videos are great for refreshing the topics I was rusty on.

[@headshotcaptain8389]

Great content, clear and concise. THANK YOU!

[@PracticalNetworking]

You're welcome =)

[@sotumodo4317]

Hey Scorpio! Excellent work. Loving your offerings. I'll be taking the ANARSI shortly and finishing my CCNP. You've become a big part of my success and I appreciate you.

[@PracticalNetworking]

Ha, hey there. Glad to hear I was a part of your learning journey. Thank you for the kind words. If you are willing... could you do me a favor? Do you mind sharing this video (or series) on Linked In, Reddit, Twitter, Facebook, or any other social media you use? As an independent creator, that would be an _enormous_ help, and I would appreciate it _greatly_ .

Waiting for the other parts of the series..

[@PracticalNetworking]

Just scheduled the next two videos to release Monday and Tuesday of this week =)

[@EyeIn_The_Sky]

Do you have videos of the order of execution/operation firewalls(or routers if it is similar) on the order the firewall does things like if the FW checks policy first then routing table or vice versa and even when NAT is done in the process?

[@PracticalNetworking]

Not specifically, no. I talk about the order NAT is applied in for ASAs and IOS Routers in my NAT courses: classes.pracnet.net/ But they don't go into the packet processing order outside of NAT, I'm afraid.

[@nomadicbydesign363]

Oh how I wish I'd found you years ago!

[@PracticalNetworking]

;)

[@PracticalNetworking]

This was the first video I ever recorded! =) Before I knew anything about creating videos. The updated version is here, with much better audio: kzbin.info/www/bejne/j3uqeIyBdrtnpqM Enjoy!

[@admin_e]

👍👍👍.

[@stefanob.889]

Hi, I wonder if you can create a playlist for the 8 parts and add the link here

[@PracticalNetworking]

Hello. The playlist already exists and can be found here: kzbin.info/aero/PLIFyRwBY_4bRkAk_BkWL3ea6lRvOn8AKs There are only 3 videos released at the time, so there are only three videos on the playlist. New videos are added to the play list as they are released.

[@rmplys5329]

CAN YOU PLEASE CREATE A VIDEO TURTORIAL RELATED TO SPANNING TREE PROTOCOL THANKS

Any plans for vpn?

[@PracticalNetworking]

At some point, I'd like to cover IKE v1. No imminent plans at the moment =(

[@TaylorSystems]

Great info, but I can't understand why you keep saying; "AX List".

[@PracticalNetworking]

You should have seen how many times I had to remove "ACL List" in editing. ;)

[@justkiddieng6317]

2:09 sir you forgot to change the source port of host B. but thats ok

[@PracticalNetworking]

Hrmm, you sure? Both those packets are from host A. Unless I'm misunderstanding your comment.

[@justkiddieng6317]

​​@@PracticalNetworkingohh my bad. LOL. But hey sir, your videos is soooo helpful. Please continue to upload more videos. I think more on security topic because I want to know more about security. Thanksss a lot. Stay safe.

[@PracticalNetworking]

Glad you're enjoying them! The TLS course is perfect for cyber security! There's a Playlist on my channel of free lessons you can demo.

[@joedarvish70]

Some of your pronunciation is hard to understand. You speak too fast and cut the words off.

[@PracticalNetworking]

You can slow down the play back speed with youtube, if it helps.

[@tahersadeghi6773]

Why do you keep pronouncing ACSLIST Instead of ACCESS LIST?!
