DESCRIPTION

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.

 

 

Local ID Type

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 the string specified in this field

 

 

Content

This field is read-only if the ZyWALL and remote IPSec router use certificates to identify

 

each other. Type the identity of the ZyWALL during authentication. The identity depends

 

on the Local ID Type.

 

IP - type an IP address; if you type 0.0.0.0, the ZyWALL uses the IP address specified

 

in the My Address field. 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 fully qualified domain name (FQDN). This value is only used for

 

identification and can be any string that matches the peer ID string.

 

E-mail- the ZyWALL is identified by the string you specify here; you can use up to 63

 

ASCII characters including spaces, although trailing spaces are truncated. This value is

 

only used for identification and can be any string.

 

 

Peer ID Type

Select which type of identification is used to identify the remote IPSec router during

 

authentication. Choices are:

 

IP - the remote IPSec router is identified by an IP address

 

DNS - the remote IPSec router is identified by a domain name

 

E-mail- the remote IPSec router is identified by the string specified in this field

 

Any - the ZyWALL does not check the identity of the remote IPSec router

 

If the ZyWALL and remote IPSec router use certificates, there is one more choice.

 

Subject Name - the remote IPSec router is identified by the subject name in the

 

certificate
