Type the identity of the ZyWALL during authentication. The identity depends on the Local ID Type.

This is not recommended in the following situations: • There is a NAT router between the ZyWALL and remote IPSec router. • You want the remote IPSec router to be able to distinguish between IPSec SA requests that come from IPSec routers with dynamic WAN IP addresses. In these situations, use a different IP address, or use a different Local ID Type. DNS - type the domain name; you can use up to 31 ASCII characters including spaces, although trailing spaces are truncated. This value is only used for identification and can be any string.
