The ASA supports a logical interface called Virtual Tunnel Interface VTI. ASA supports policy-based VPN with crypto maps in version 82 and later.
We will be creating a route based connection using IKEv2 and a VTI interface.
Cisco asa route based vpn azure. This allows dynamic or static routes to be used. I am going to assume you are already using Azure and you already have a Virtual Network in. Firstly the implementation of a Route-based VPN with an ASA 5505 requires the use of Traffic Policy Selectors.
Microsoft Azure MFA seamlessly integrates with Cisco ASA VPN appliance to provide additional security for the Cisco AnyConnect VPN logins. We are also going to focus on how to achieve this using ASDM. Essentially the difference between route based and policy based VPN is in the negociation of the proxy during the IKE negociation.
Then assign it to a newly created VM. The sample configuration connects a Cisco ASA device to an Azure route-based VPN gateway. Please refer to Configure IPsecIKE policy for detailed instructions.
If you have already done this you can skip over these steps. Cisco ASA or PIX but that would not work for what I want to do Normally a Cisco ASA or PIX for the folks who were around a whily ago allows policy based VPNs. For route-based VPN gateways created using the Azure Resource Management deployment model you can specify a custom policy on each individual connection.
As an alternative to policy based VPN a VPN tunnel can be created between peers with Virtual Tunnel Interfaces configured. Cisco Firepower Management Center. When configured this requires you to define a custom IPSec Policy in Azure for the connection and then apply the policy and the Use Traffic Policy Selectors option to the connection.
Consult your VPN device vendor specifications to verify that the IKEv2 policy is supported on your on-premises VPN devices. Azure Route-Based VPNs actually do support Cisco ASAs but you have to configure Policy Based Traffic Selectors on the Azure Gateway. On the ASA configure a static route pointing to 1012254 out the VTI Tunnel.
NOTE Further information on Azure Virtual Networks and the different deployment models can be found here. In this example 1921681002 is within the same subnet as the VTI. Choisissez soit de configurer IKEv1 IKEv2 Route Based avec VTI soit IKEv2 Route Based avec Use Policy-Based Traffic Selecteurs crypto map sur ASA.
Within Azure the configuration of the VPN centres around Azure Virtual Networks. In the following steps we will create a VNet and subnet. Suivez les etapes de configuration ci-dessous.
Learn about Cisco ASAv route based VPN Demo connecting AWS and Azure ASAv AWS crypto ikev1 enable management. Even though no device has that IP address the ASA will install the route pointing out the VTI interface. The connection uses a custom IPsecIKE policy with the UsePolicyBasedTrafficSelectors option as described in this article.
Route AZURE 1012254 255255255255 1921681002 1. Crypto ikev1 policy 10 authentication pre-share encryption aes hash sha group 2. The sample requires that ASA devices use the IKEv2 policy with access-list-based configurations not VTI-based.
Additionally you must clamp TCP MSS at 1350. Azure currently restricts what IKE Internet Key Exchange version you are able to configure based upon the VPN selected method. This supports route based VPN with IPsec profiles attached to the end of each tunnel.
Microsoft Azure supports route-based policy-based or route-based with simulated policy-based traffic selectors. Cisco Firepower Threat Defense. In this post we are going to link an Azure Virtual Network to on an premise network via a Cisco ASA.
