The outside interface of ASA1 is assigned a dynamic IP address by the service provider over DHCP, while the outside interface of ASA2 is configured with a static IP address . This section will outline the process for configuring a Site-to-site VPN between an MX Security Appliance and a Cisco ASA using the command line interface on the Cisco ASA. Note : We strongly recommend running ASA 8.3 or above as there is a possibility the tunnel will tear down prematurely on earlier versions.

Note. The sample configuration connects a Cisco ASA device to an Azure route-based VPN gateway. The connection uses a custom IPsec/IKE policy with the UsePolicyBasedTrafficSelectors option, as described in this article.. The sample requires that ASA devices use the IKEv2 policy with access-list-based configurations, not VTI-based. Consult your VPN device vendor specifications to verify that
