Select Dynamic Address if the remote IPSec router has a dynamic IP address
(and does not use DDNS).

8 - 32 alphanumeric characters or ,;|`~!@#$%^&*()_+\{}':./<>=-".
•
16 - 64 hexadecimal (0-9, A-F) characters, preceded by “0x”.
If you want to enter the key in hexadecimal, type “0x” at the beginning of the key.
For example, "0x0123456789ABCDEF" is in hexadecimal format; in
“0123456789ABCDEF” is in ASCII format. If you use hexadecimal, you must
enter twice as many characters as listed above.

Certificate
Select this to have the ZyWALL and remote IPSec router use certificates to
authenticate each other when they negotiate the IKE SA. Then select the
certificate the ZyWALL uses to identify itself to the remote IPsec router.
This certificate is one of the certificates in My Certificates. If this certificate is
self-signed, import it into the remote IPsec router. If this certificate is signed by a
CA, the remote IPsec router must trust that CA.

Note: The IPSec routers must trust each other’s certificates.
The ZyWALL uses one of its Trusted Certificates to authenticate the remote
IPSec router’s certificate. The trusted certificate can be a self-signed certificate or
that of a trusted CA that signed the remote IPSec router’s certificate.

•
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.

spaces, although trailing spaces are truncated. This value is only used for
identification and can be any string.
