SEC0027 - ASA Remote Access IPSec VPN with Pre-Shared Key and Certificate

The video demonstrates configuration of remote access IPSec VPN with Windows software client on Cisco ASA firewall. 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, IPSec over UDP and IPSec over TCP. The order of precedence on encapsulation types will be investigated when they are all enabled simultaneously.

SEC0022 - Router Remote Access IPSec VPN with Pre-Shared Key and Certificate

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.

SEC0021 - Router EZVPN with Cisco Tunneling Control Protocol (cTCP)

The video shows you how to enable Cisco Tunneling Control Protocol, also known as, IPSec over TCP, on Cisco router Easy VPN (EZVPN) connection. cTCP can potentially be a solution when you need to establish a VPN through a device or network that does not support ESP protocol. TCP encapsulation makes IPSec traffic NAT-friendly at the cost of additional overhead of TCP header. In this lab, we will simulate an unsupported network using ACL to block ESP and shows how cTCP provides a workaround.

SEC0020 - Router EZVPN with Dynamic Virtual Tunnel Interface (DVTI)

The video desmonstrates the configuration of Easy VPN (EZVPN) using Dynamic Virtual Tunnel Interface (DVTI) on Cisco routers and explains its benefit over the conventional EZVPN with 'crypto map' or tunnel interface with GRE. Here we introduce the concept of Virtual-Template. The second half of the video shows example of additional features that you can implement with VTI using QoS and multicasting.

SEC0019 - Router EZVPN with Network-Extension Mode, Multiple Subnets, and NAT Support

The video demonstrates three different operational modes available on Cisco Easy VPN (EZVPN) router hardware client, namely Client, Network Extension, and Network Extension Plus, and explains when they should be used. We will also look at how to support multiple remote subnets, and NAT compatibility specifically when you run Network Extension or Network Extension Plus. These configurations only pertain to the hardware client side.

SEC0018 - EZVPN Connect and XAuth Mode Options

The video demonstrates various methods of EZVPN hardware client to initiate an IPSec connection. In this lab, the headend router is setup with Easy VPN (EZVPN) with Pre-shared key authentication, while the client is configured to run in Client Mode. We then explore different 'connect' and 'xauth' configuration options on the client side.

SEC0017 - ASA EZVPN with Pre-Shared Key & Certificate

The video walks you through configuration of Easy VPN (EZVPN) with Pre-shared key and certificate authentication on a Cisco headend ASA firewall. The hardware client router is running Client Mode and configured to automatically connect using a locally stored credential. This video is a counterpart of SEC0015 and SEC0016 with the headend router. Here we introduce the concept of 'group-policy' and 'tunnel-group' that are unique to the ASA, while most crypto command syntax is very similar to those on a router.

SEC0016 - Router EZVPN with Certificate

The video walks you through configuration of Easy VPN (EZVPN) with Certificate authentication on a Cisco headend router. The hardware client router is running Client Mode and configured to automatically connect. Headend router already has a certificate installed through SCEP (See SEC0014 - Certificate Installation on Router and ASA), while we demonstrate a manual certificate import on the hardware client. XAuth can also be enabled concurrently, although we have XAuth disabled in this lab.

SEC0015 - Router EZVPN with Pre-Shared Key and XAuth

The video walks you through configuration of Easy VPN (EZVPN) with Pre-shared key authentication on a Cisco headend router. The hardware client router is running Client Mode and configured to automatically connect using a locally stored credential. We demonstrate unique characteristics of Client mode where connections can only be initiated from the remote client as the client router performs PAT to the source IP. Any resources local to the client is inaccessible from the headend side.
