S3E1_IPSEC VPN_Aggressive Mode_Why? and how? 

After going through many videos I must say this is best explained on the internet about IPsec messages. Sir, could you please make one video on quick mode messages as well.

Crystal clear explained

Hi, Thanks for such informative videos. Could you please also advise how the NAT-D is incorporated here? I assume you missed that part inadvertently?

You have a gift for expressing things clearly. Thank you!

Your way of explanation is osum to understand. Could you clarify the below query? In MM5, we encrypt the hash + ID I. If I use NAT device then the responder will do the hash matching with the Natted ip only. So hash will fail know. So, please explain

Thank you so much for the brilliant explanation so far... Sir, Please make video on quick mode messages as well.

many thanks for the video.... Expectation are high sir...please explain about Ikev2 and Why child SA is generated.

Seriously , man i am eagerly waiting for your video specially aggressive mode !

If Both peer IP known and fixed, we can go for Main Mode. But what if remote end ip gets changed by ISP frequently or its not fixed, like HUB-SPOKE. I mean to say we dont know the fixed IP, we can use identity as HOSTNAME/FQDN. and for spoke side ,HUB has fixed ip. But for HUB side, spoke doesn't have fixed ip, its dynamic. we can use aggressive mode site to site.

Could you please upload phase2 videos

Thank you for this video .

Please also upload quick mode video.

Pls upload video on Phase II (Quick Mode)

Sir is the PHASE 2 Same in main and aggressive mode?if not then please upload phase 2 using aggressive mode.....please reply fast.
