How can I do that and have each zone on a different subnet ?Any advice/example would be greatly appreciated. Network Topology: Point to Point. For example, on some models the hardware switch interface used for the local area network is called lan, while on other units it is called internal. Each interface on the ASA is a security zone so by using these security levels we have different trust levels for our security zones. Note: This eliminates one of the problems that the combined use of Layer 2 Tunneling Protocol (L2TP) and IPsec is intended to solve. Next Lesson Cisco ASA ASDM Configuration.

In this example when you select endpoints, Node A is the FTD, and Node B is the ASA. Enable IKEv2 on the outside interface of the ASA: Crypto ikev2 enable outside. Sophos Firewall doesn't support traffic-based re-keying so the remote peer must not have it enabled (an issue especially seen when the remote peer is a Cisco ASA or a Cisco Router). To get pastthis you need to make a change to the trustpoint on the ASA. The Initiator starts the IKE_AUTH exchange and starts generation of the authentication payload.
