Specify Extranet for all VPN peer endpoints that are not managed by the same FMC as Node A. To test VPN, let's initiate some traffic from the Client to the server to verify that the tunnel is working. ASA Route Based VPN Route based VPN Last Updated: [last-modified] (UTC) Introduction As discussed in the Policy Based VPN article, the ASA's do not use tunnel interfaces for a site-to-site VPN. Route-Based VPN As the name implies a route-based VPN is a connection in which a routing table entry decides whether to route specific IP connections (based on its destination address) into a VPN tunnel or not. For further clarification contact Microsoft Azure support. First, verify the correct version of IKE is triggered and that the ike-common process shows no relevant errors: If no ike-common debug output is seen when VPN traffic is initiated, this means traffic is dropped before it reaches the crypto process or crypto ikev1/ikev2 is not enabled on the box. Note:Microsoft has published information that conflicts with regards to the particular IKEv2 phase 1encryption, integrity, and lifetime attributes used by Azure. Step 2.2. NAT exempt does not match when I choose outside physical interface as outgoing interface. However, you have to set the IP address on the tunnel interface manually after that. You also have the option to opt-out of these cookies. For further clarification contact Microsoft Azure support. IKEv2 attribute information from Microsoft that conflicts isvisible here. Great article. You are routing the traffic to Azure, the fact you are encrypting it is neither here nor there. These cookies do not store any personal information. The encryption domain is set to allow any traffic which enters the IPsec tunnel. Step 5. dst: 0:0.0.0.0/0.0.0.0:0 set snmp-index 8 The on-premises networks connecting through policy-based VPN devices with this mechanism can only connect to the Azure virtual network; they cannot transit to other on-premises networks or virtual networks . Traditionally, the ASA has been a policy-based VPN which in my case, is extremely outdated. If there are no Subnets behind the ASA (everything is NATed), what should I enter on Azure side to address space field? Just configure the remote router, group name, username /password and you are ready to go.The policy is then implemented in the configuration interface for each . Its like a GRE tunnel, see this post https://www.petenetlive.com/KB/Article/0000951 here Ive got the SAME IP on both ends of the tunnel and it still works. This article will deal with Route Based, for the older Policy Based option, see the following link; Microsoft Azure To Cisco ASA Site to Site VPN. The tunnel comes up but there is no data received on the FG side of the tunnel. Route-based VPN is an alternative to policy-based VPN where a VPN tunnel can be created between peers with Virtual Tunnel Interfaces. Also, from the main office I have a policy-based VPN tunnel with Azure from an ASA. For further clarification, contact Microsoft Azure support. Configuration of VPN Between R1 and R2. In that case would you still need to use SLA to alter the route or would the interface go down with a loss of connectivity to Azure and fail down to the next higher cost route? set ip6-other-flag enable With your virtual network selected >Subnets > +Gateway Subnet. set dhgrp 21 SK_ei: c8f642478cf00102-3ca79b53e769a0ca-8c3e64d8fc6e6878-64e38bebc769873c-daec86e8 Configure the Transform Set (TS), which must involve the keywordIKEv1.
