DESCRIPTION
In order to use Certificate for IPsec authentication, you need to add new host
certificates in the Firewall / Security > Certificate screen.
Select this to have the SBG and remote IPsec router use certificates to authenticate
each other when they negotiate the IKE SA. Then select the certificate the SBG uses
to identify itself to the remote IPsec router.
This certificate is one of the certificates in Certificate. 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 SBG uses one of its Trusted CA 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 SBG and remote IPsec router use certificates to identify
each other. Select which type of identification is used to identify the SBG during
authentication. Choices are:
IPv4 - the SBG is identified by an IP address.
DNS - the SBG is identified by a domain name.
Email Address - the SBG is identified by the string specified in the Content field.
My Address - the SBG is identified by he IP address specified in the My Address field.
This field is read-only if the SBG and remote IPsec router use certificates to identify
each other. Type the identity of the SBG during authentication. The identity depends
on the Local ID Type.
IPv4 - type an IP address. This is not recommended in the following situations:
• There is a NAT router between the SBG 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.
Email Address - the SBG 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.
Select which type of identification is used to identify the remote IPsec router during
authentication. Choices are:
IPv4 - the remote IPsec router is identified by an IP address.
DNS - the remote IPsec router is identified by a domain name.
Email Address - the remote IPsec router is identified by the string specified in this field.
Any - the SBG does not check the identity of the remote IPsec router If the SBG and
remote IPsec router use certificates, there is one more choice.
