In computing, Internet Key Exchange is the protocol used to set up a security association (SA) Most IPsec implementations consist of an IKE daemon that runs in user space and an storage containing configuration information, such as the IPsec endpoint addresses, IKEv1 consists of two phases: phase 1 and phase 2. IKE Phase supports the use of preshared keys or digital certificates (which use public key infrastructure, PKI) for mutual authentication of the VPN peers. When creating an ASA IPsec VPN, there will be times when Phase 2 does not match between the peers. Select the tunnel interface, the IKE gateway, and the IPSec Crypto profile to make sure the Proxy-ID is added, otherwise phase 2 will not come up.
