The two ZyWALLs in this example cannot complete their negotiation because ZyWALL B’s
Local ID type is IP, but ZyWALL A’s Peer ID type is set to E-mail. An ID mismatched
message displays in the IPSec log.

19.8 IKE Phases
There are two phases to every IKE (Internet Key Exchange) negotiation – phase 1
(Authentication) and phase 2 (Key Exchange). A phase 1 exchange establishes an IKE SA and
the second one uses that SA to negotiate SAs for IPSec.
Figure 147 Two Phases to Set Up the IPSec SA
In phase 1 you must:
• Choose a negotiation mode.
• Authenticate the connection by entering a pre-shared key.
• Choose an encryption algorithm.
Peer ID type: IP Peer ID type: E-mail
