The ZyWALL and remote IPSec router use a pre-shared key in the authentication process,

The ZyWALL and the remote IPSec router must use the same pre-shared key.
Router identity consists of ID type and ID content. The ID type can be IP address, domain
name, or e-mail address, and the ID content is a specific IP address, domain name, or e-mail
address. The ID content is only used for identification; the IP address, domain name, or e-mail
address that you enter does not have to actually exist.
The ZyWALL and the remote IPSec router each has its own identity, so each one must store
two sets of information, one for itself and one for the other router. Local ID type and ID
content refers to the ID type and ID content that applies to the router itself, and peer ID type
and ID content refers to the ID type and ID content that applies to the other router in the IKE

In the following example, the ID type and content match so the ZyWALL and the remote
IPSec router authenticate each other successfully.
