Do we have any separate in depth playlist like BGP for IPSEC because the way you explained BGP was so cool.

[@user-fe3ho8cg4j]

lol prayed a bit and got IT things no bad

[@zhanko73]

Very good videos. I only have 1 suggestion. Probably the explaining text that are handwritten could be typed as 90% unreadable. Yes, there is a voice in the video that is written down so it could explain, however everybody speaks different learnt english and sometimes there were some cases when neither I understand a technical expression nor I can read it or just wanted to re-read what was written. :( Otherwise good videos. Thanks for that.

Hi Sikandar,
Nice eplaination !!
I would like to understand the following:
1) In IKE V1, ISAKMP message 5 and 6 , Does it carry the IP address of IPSEC Peer device for authenticatication ?
2) If so, With NAT-T in place, How the authentication gets succeed as the Public IPaddress of peer device sent in Identification message doesn’t match with the Private IP of the peer device ?
Regards,
Hariharan

Thanks for this video but not agree with point asymmetric authentication details please check, it's not like that u can use psk one side and certificate otherwise🙏👍

[@vibeshot.]

So how it works? Please comment, I have to understand, clear me.

[@nandhakumar8230]

Yes that is my question as well. I implemented lot of VPN tunnels with different vendor firewalls, I have never seen asymmetric authentication supported even in IKE v2. Does it support in cisco fw or routers alone???
For sure, asymmetric authentication will not work in interoperable devices.

[@z0nerider]

The major difference between IKE versions 1 and 2 lies in terms of the authentication method they allow. IKEv1 allows only one type of authentication at both VPN ends (that is, either pre-shared key or certificate). However, IKEv2 allows asymmetric authentication methods to be configured (that is, pre-shared-key authentication for the originator, but certificate authentication for the responder) using separate local and remote authentication CLIs.
Further, you can have different pre-shared keys at both ends. The Local Pre-shared key at the HQ-ASA end becomes the Remote Pre-shared key at the BQ-ASA end. Likewise, the Remote Pre-shared key at the HQ-ASA end becomes the Local Pre-shared key at the BQ-ASA end.

[@babujohn6655]

your explaination for asymmetric authentication i feel is not correct .assymmetric encryption is not using different keys but having public and private keys (pki)

[@gutopesset]

I think that assymetric auth != assymetric encryption

[@clashwithsmith2002]

Can u give me tuition for ccna? I will pay you sir.
. Please start online classes so that we can join u and will learn from you.. Allah apko aur ilm de.

[@techlearner4806]

Both.
