DESCRIPTION
Enter the WAN IP address of your Prestige. The VPN tunnel has to be rebuilt if
this IP address changes.
The following applies if this field is configured as 0.0.0.0:
The Prestige uses the current Prestige WAN IP address (static or dynamic) to set
up the VPN tunnel.
If the WAN connection goes down, the Prestige uses the dial backup IP address
for the VPN tunnel when using dial backup or the LAN IP address when using
traffic redirect. See the chapter on WAN for details on dial backup and traffic
redirect.
Select IP to identify the remote IPSec router by its IP address.
Select DNS to identify the remote IPSec router by a domain name.
Select E-mail to identify the remote IPSec router by an e-mail address.
The configuration of the peer content depends on the peer ID type.
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 Prestige will
use the address in the Secure Gateway Address field (refer to the Secure
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 Prestige to distinguish between VPN connection requests that
come in from remote IPSec routers with dynamic WAN IP addresses.
Type the WAN IP address or the URL (up to 31 characters) of the IPSec router
with which you're making the VPN connection. Set this field to 0.0.0.0 if the
remote IPSec router has a dynamic WAN IP address (the Key Management field
must be set to IKE).
In order to have more than one active rule with the Secure Gateway Address
field set to 0.0.0.0, the ranges of the local IP addresses cannot overlap between
rules.
If you configure an active rule with 0.0.0.0 in the Secure Gateway Address field
and the LAN's full IP address range as the local IP address, then you cannot
configure any other active rules with the Secure Gateway Address field set to
0.0.0.0.
Select ESP if you want to use ESP (Encapsulation Security Payload). The ESP
protocol (RFC 2406) provides encryption as well as some of the services offered
by AH. If you select ESP here, you must select options from the Encryption
Algorithm and Authentication Algorithm fields (described below).
