Vantage CNM User's Guide
DESCRIPTION
The configuration of the peer content depends on the peer ID type.
Do the following when you set Authentication Key to Pre-shared
Key.
• For IP, type the IP address of the computer with which you will
make the VPN connection. If you configure this field to 0.0.0.0
or leave it blank, the device will use the address in the Remote
Gateway Address field (refer to the Remote Gateway
Address field description).
• For DNS or E-mail, type a domain name or e-mail address by
which to identify the remote IPSec router. Use up to 31 ASCII
characters including spaces, although trailing spaces are
truncated. The domain name or e-mail address is for
identification purposes only and can be any string.
It is recommended that you type an IP address other than 0.0.0.0
or use the DNS or E-mail ID type in the following situations:
• When there is a NAT router between the two IPSec routers.
• When you want the device to distinguish between VPN
connection requests that come in from remote IPSec routers
with dynamic WAN IP addresses.
Do the following when you set Authentication Key to Certificate.
• For IP, type the IP address from the subject alternative name
field of the certificate the remote IPSec router will use for this
VPN connection. If you configure this field to 0.0.0.0 or leave it
blank, the device will use the address in the Remote Gateway
Address field (refer to the Remote Gateway Address field
description).
• For DNS or E-mail, type the domain name or e-mail address
from the subject alternative name field of the certificate the
remote IPSec router will use for this VPN connection.
• For Subject Name, type the subject name of the certificate the
remote IPSec router will use for this VPN connection. Use up
to255 ASCII characters including spaces.
• For Any, the peer Content field is not available.
• Regardless of how you configure the ID Type and Content
fields, two active SAs cannot have both the local and remote IP
address ranges overlap between rules.
Select this check box to activate extended authentication.
