IP Sec VPN Fundamentals

This video steps through the architecture of IPSEC VPNs. IPsec VPN negotiation occurs in two phases. In Phase 1, participants establish a secure channel in which to negotiate the IPsec security association (SA). In Phase 2, participants negotiate the IPsec SA for authenticating traffic that will flow through the tunnel.

Finally I found what I consider the best tutorial to understand how, step-by-step a VPN IPSec connection is built. Fantastic and congrats mate.

[@LearnCantrill]

Glad it helped!

[@moldisocks1521]

Best tutorial I've seen in a while. Super thorough, clearly explained and with great diagrams! 🙌😊

[@LearnCantrill]

Glad you enjoyed it!

[@Mrs.Nizbits]

Getting ready to take my Net + this Tuesday and was struggling with IPSEC but not any more after watching this video Thank you so much !!!!

[@LearnCantrill]

Glad you found it useful.

[@darkmadarauchiha]

You are a life saver. This is the 4th video I have watched on this stuff...Wish I found you first!

[@IronAndDiesel]

Needed a straight to the point refresher on IPsec. Haven’t worked with VPNs in many years. Good video!

[@garaamir7579]

who the hell is julie ? where is alice ??

[@honorenoubissie9738]

BOB doing sketchy things

[@amilcarchissola2262]

I wonder the same 😂😂😂😂😂. Julie came from nowhere

[@WhiteHat-1337]

The typical Alice and Bob is used as an example, but here, I feel Bob really needs his messages to be encrypted.

[@thomasmathew4748]

Bob

[@Roger-d5o]

Alice doesn't live here anymore.

[@rockinblue978]

Just started Adrian's AWS SAA course and he explains everything clearly and consistently just as he's done here. After trying other training providers, I can honestly say Adrian is by far the best I've seen if you want to become an Architect.

[@LearnCantrill]

thanks, appreciate that.

[@KyleDenning]

Brillant, thank you. Learning how to do this for my job as a Level 2 Engineer. Now understand how it all works, so thank you!

[@LearnCantrill]

Glad it helped!

[@subodhvaid4583]

Amazing, hats off ! Best video on IPSec ever made.

[@TheN0mad93]

Thanks so much. I have been supporting a huge platform that is using IPSEC tunnels and I was puzzled everytime I troubleshoot them and see IKE1 & IKE2 in logs and unfortunately I didn't find quite the source to understand except now. Thanks so much this was beneficial.

[@LearnCantrill]

glad it helps.

[@AndrewEmmett]

Brilliant Video mate. Clear, concise and perfectly pitched and someone with IT experience, but with gaps in this area. Really struggled to understand the Geek documentation on this 😂😂😂. But you’ve made days of reading all make sense.

[@hungryinthetumtum]

Thanks!

[@lunarjordan]

Cannot wait to start your AWS courses Adrian, amazing work on these technical fundamental videos! Using this as a refresher while I go over the NSE4. After I finish that, going straight into your AWS SAA course! Thank you so much for your teaching.

[@LearnCantrill]

no problem at all, glad you find it useful

[@محمدممدوحوقاد]

Amazing...very detailed and to the point...Thanks ! Loved it !

[@LearnCantrill]

Glad you liked it!

[@rubo111]

Nice video, done well presenting a difficult concept.
One question though. Does each IPSEC SA pair use the same key for each unidirectional SA or does each pair use a unique key per SA?
I couldn't get a straight answer out of chatGPT but it seemed to suggest unique key per SA in a pair.

[@sergiuchiuchiu6692]

@LearnCantrill Is it possible for a malicious entity to intercept that certificate exchange in the IKE phase 1 and impersonate one of the users using that?

[@alteshaus3149]

amazing... truly amazing work, thanks so much
