Hi all, I am having a bit of trouble understanding the reasoning behind L2TP/IPSec. I understand that L2TP is not a very secure protocol which is why it is a good idea to encapsulate it in an IPSec tunnel, however, in that case why not just use IPSec on its own?
I'm sure there is a logical answer to that question but so far I have been unable to find it. Any information would be greatly appreciated. Thank you.
