Chapter 25 IPSec VPN Table 121 Configuration > VPN > IPSec VPN > VPN Gateway > Edit (continued) LABEL DESCRIPTION Pre-Shared Key Select this to have the ZyWALL and remote IPSec router use a preshared key (password) to identify each other when they negotiate the IKE SA. Type the pre-shared key in the field to the right. The preshared key can be • 8 - 32 alphanumeric characters or • 8 - 32 pairs of 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 since you need to enter pairs. Certificate The ZyWALL and remote IPSec router must use the same pre-shared key. 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. Local ID Type 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. This field is read-only if the ZyWALL and remote IPSec router use certificates to identify each other. Select which type of identification is used to identify the ZyWALL during authentication. Choices are: IP - the ZyWALL is identified by an IP address DNS - the ZyWALL is identified by a domain name E-mail - the ZyWALL is identified by an e-mail address 460 ZyWALL USG 2000 User's Guide
