• ASA 1000V VPN - IKEv1 Phase1/2
• ASA 1000V VPN - IPSec
• ASA 1000V NAT Bypass (ie. Self-NAT)

• VPN Interface Policy only take affect when applied to an outside interface

• ASA 1000V VPN Device Policy (Phase 1)
  • IKE Policy

The video takes the site-to-site L2L IPSec VPN to the next level by combining what we have learnt from the previous videos with the concept of Virtual Routing Forwarding (VRF). We will look at how you can segregate different type of L2L VPN into their own logical routing domain, while they all share the same physical hardware. Basic understanding of VRF is recommended before viewing this video

The video walks you through configuring site-to-site (L2L) IPSec VPN tunnel between Cisco router and ASA firewall using certificate authentication. You will see that choosing the type of identity to send and match becomes very important as the certificate does not get exchanged until later in Phase 1 negotiation. Using aggressive mode allows the device identity contained in the certificate to be revealed sooner but at a risk of identity exposure. Aggressive mode will also be reviewed in this video.

The video walks you through configuring site-to-site (L2L) IPSec VPN tunnel between Cisco router and ASA firewall. This is probably the simplest form of L2L IPSec using 'crypto map' and crypto ACL to match interesting traffic. You will see that you can apply the same configuration thought process to both router and ASA, while ASA having slight variation on the use of Tunnel-group and Group-policy. We will also look at how to restrict traffic over the tunnel using an access-list (ACL).
