This tutorial demonstrates how to configure GRE over IPsec to connect two remote sites and to allow them to exchange routes dynamically with EIRGP.

Lock-and-key access allows you to set up dynamic access lists that grant access per user to a specific source/destination host through a user authentication process(telnet login authentication).
See cut-through proxy, They call it like that in the ASA world.

The video demonstrates configuration of remote access IPSec VPN with Windows software client on Cisco router. We will look at both simple pre-shared key authentication as well as using client certificate. The client is placed behind a NAT router to demonstrate the significance of NAT Transparency, and compare it to raw IPSec and cTCP (IPSec over TCP). The video finishes off by showing how client can be allowed access to local subnet when a non-split tunnel is used.
Topic includes
- Easy VPN (EZVPN) with Software IPSec Client
- Client Pre-Shared Key and Certificate Authentication
- NAT Transparency (UDP 4500)
- cTCP aka IPSec over TCP
- 'include-local-lan' Option when not using Split Tunnel

"We sort of have two main categories of VPN. 1) Lan to Lan (aka Site to Site) and 2) Remote access. With lan to lan VPN's, there is some device (router, firewall, concentrator) that terminates bot ends of the connection. With Remote access, there is a piece of software installed on a PC/Laptop on one end and the other end would be terminated into a router, firewall or concentrator"
