I'm a computer science student and this video helped me understand tunneling so much better thank you. Reading out of a textbook is rarely the best approach to learning something!

[skwidfingaz]

This is SUCH a great demonstration of tunnelling for a student to understand tunnelling. Thank you.

One of my favorite quotes:
"If you can't explain it simply, you don't understand it well enough." -Albert Einstein

Keith is an amazing teacher

I logged in to my account just to give this video a like - enough said. Explaining concepts so clearly is something few people can do - thanks!

Forgive my unprofessional language for a moment here, but I have to say it... you are just so fucking good, Keith.

I've been reading and watching videos trying to wrap my head around tunneling for about an hour now, then I found your video and 8mins later, I'm crystal clear about what's actually happening when we discuss tunneling.

It's no longer this abstract concept in my mind, but instead is clearly defined now.

Thank you, Keith.

You are truly amazing man.

Keith, I passed my ccna on Tuesday. Your channel played a big part. Thank you for the great content. I will be signing up with cbt nuggets for ENCOR.

Configuring GRE and IPSec is very fun. That was my favorite section when I was studying for the CCNA. That and FHRP's. Thank you Keith for all of your hard work!

That's funny, I work with a number of different Optical Carrier Networks, one of them is an OC-12 Transport called Jungle-mux, unrelated to tunneling, but made me chuckle :)

[priest_of_art]

That is what needed. Although I am not fluent in English, I've got you straight. Thanks a lot
