![]() object-group network local-networkĪccess-list asa-router-vpn extended permit ip object-group local-network It protects the outbound packets that match a permit Application Control Engine (ACE) and ensures that the inbound packets that match a permit ACE have protection. The ASA uses Access Control Lists (ACLs) in order to differentiate the traffic that should be protected with IPSec encryption from the traffic that does not require protection. In order to configure the IKEv1 preshared key, enter the tunnel-group ipsec-attributes configuration mode: tunnel-group 172.17.1.1 type ipsec-l2lĬonfigure the ACL for the VPN Traffic of Interest In order to enable IKEv1, enter the crypto ikev1 enable command in global configuration mode: crypto ikev1 enable outsideĬonfigure the Tunnel Group (LAN-to-LAN Connection Profile)įor a LAN-to-LAN tunnel, the connection profile type is ipsec-l2l. Typically, this is the outside (or public) interface. You must enable IKEv1 on the interface that terminates the VPN tunnel. Note: If you do not specify a value for a given policy parameter, the default value is applied. If the lifetimes are not identical, then the ASA uses the shorter lifetime. For IKEv1, the remote peer policy must also specify a lifetime less than or equal to the lifetime in the policy that the initiator sends. ![]() Note: An IKEv1 policy match exists when both of the policies from the two peers contain the same authentication, encryption, hash, and Diffie-Hellman parameter values. In order to configure the Internet Security Association and Key Management Protocol (ISAKMP) policies for the IKEv1 connections, enter the crypto ikev1 policy command: crypto ikev1 policy 10 You can use a ping in order to verify basic connectivity.Ĭonfigure the IKEv1 Policy and Enable IKEv1 on the Outside Interface Note: Ensure that there is connectivity to both the internal and external networks, and especially to the remote peer that will be used in order to establish a site-to-site VPN tunnel. If the ASA interfaces are not configured, ensure that you configure at least the IP addresses, interface names, and security-levels: interface GigabitEthernet0/0 The information in this document uses this network setup: This section describes how to complete the ASA and IOS router CLI configurations. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment.
