ZyWALL 10~100 Series Internet Security Gateway

VPN/IPSec Setup

29-5

Table 29-3 Peer Fields

LOCAL ID TYPE=

CONTENT=

N/A, do not enter anything.

DNS

Type a domain name (up to 31 characters) by which to identify the remote
IPSec router.

E-mail

Type an e-mail address (up to 31 characters) by which to identify the remote
IPSec router.

The domain name or e-mail address that you use in the Content field is used for identification purposes
only and does not need to be a real domain name or e-mail address. The domain name also does not
have to match the remote router’s IP address or what you configure in the Secure Gateway Addr field
below.

Two IPSec routers must have matching ID type and content configuration in order to set up a VPN tunnel.
The two ZyWALLs in this example can complete negotiation and establish a VPN tunnel.

Table 29-4 Matching ID Type and Content Configuration Example

ZYWALL A

ZYWALL B

Local ID type: IP

Local ID content: N/A

Local IP address: 1.1.1.1

Local IP address: 1.1.1.2

Peer ID type: IP

Peer ID content: N/A

Peer IP address: 1.1.1.2

Peer IP address: 1.1.1.1

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.
