ZyWALL 5/35/70 Series User’s Guide

Table 97 Matching ID Type and Content Configuration Example

ZYWALL A

ZYWALL B

 

 

Peer ID type: IP

Peer ID type: E-mail

 

 

Peer ID content: 1.1.1.2

Peer ID content: tom@yourcompany.com

 

 

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.
