Understanding IPSec, L2TP, IKEv1, and IKEv2

Posted on by

I’m learning about IPSec at the moment. Unfortunately there’s a few roadblocks to my understanding:

  • Vague explanations
  • Not enough detail
  • No practical wisdom
  • Lack of examples

I’ve made a lot of progress, but I’m sure I don’t understand some things completely since I can’t answer these questions:

  • I don’t understand why you would require L2TP over IPSec when you can just use raw IPSec with IKE (What are some scenarios for each, advantages, disadvantages, and scenarios where IPSec/IKE wouldn’t work)
  • Does an IPSec/L2TP VPN use IKE or IKEv2 to set up IPSec, to then tunnel L2TP over it
  • I can’t think of any scenarios where L2TP would be useful
  • I don’t understand why you can use IPSec with IKEv2 as a vpn, but not with IKEv1

If you can help me fill in the gap/s on why this is the case.

IPSec vs L2TP question 1 – in my opinion not answered: What’s are the advantages of L2TP/IPSEC over plain IPSEC?

IPSec vs L2TP question 2 – in my opinion not answered: why use L2TP/IPsec insted of just IPsec
