L2TP while it is a VPN protocol, it is not IPSec. More appropriately it is Microsoft's implementation by combining their own PPTP with Cisco's Layer-2 Forwarding (L2F) protocol. IPSec is also a VPN protocol. Technically they are not one and the same. It is more commonly accepted and used due to it's strength and flexibility. L2TP can integrate with an IPSec aware gateway. There are 3 standard VPN protocols, Layer-2 PPPoE/PPP, PPTP and IPSec. I would classify L2TP in the non-standard category like cIPe and VTun. (borrowed from building Linux vpn's by new riders) In case your curious, IPSec consists of 3 parts. IKE (internet key exchange), AH (Authentication Header) and ESP (Encapsulating Security Payload).

Do most VPN solutions that use IPSec also use L2TP? Or are there other protocols that also use IPSec? I see a lot of mention of IPSec in the sales literature but no mention of L2TP.
