Ipsec ikev2 frente a isakmp

Esta publicación nos habla sobre los conceptos de IKE y ISAKMP ampliamente utilizados en IPSec. Pasemos a la información. Las claves utilizadas para el cifrado y autenticación de VPN IPSec están configuradas manualmente.Para garantizar la seguridad a largo plazo de una VPN IPSec, estas claves deben ser modificadas y reemplazadas a menudo.

We will first use the crypto ikev2 policy command to enter IKEv2 policy configuration mode, ASA2(config-tunnel-ipsec)# ikev2 remote-authentication pre-shared-key 32fjsk0392fg. Finally, we will create a crypto map linking the access list, Configuring a VPN for L2TP/IPsec with IKEv2 in the WebUI.

To install IPSEC IKEv2, we should install libreswan package Many operating systems support an L2TP/IPsec VPN out-of-the-box.

If the IPsec tunnel is not UP, check that the ISAKMP policies match with the remote peers.

Only clients running Windows 7, StrongSwan 4.3 and Aruba VIA support IKEv2. For additional information on the authentication types supported by these clients, see “Working with IKEv2 Clients ”.

The IKEv2 remains stable, but using the same configurations from IKEv1 the tunnel never comes up. An IKEv2 profile is a repository of the nonnegotiable parameters of the IKE SA. An IKEv2 profile must be attached to either crypto map or IPSec profile on both IKEv2 initiator and responder.

IKEv2 is the part of IPsec that establishes a security association between your device and, usually, the VPN server. That means it allows the devices to determine what security measures they’ll use to make a VPN connection.
