Authentication
Method
My IP Address Enter the ZyXEL Device's static WAN IP address (if it has one) or leave the field
set to 0.0.0.0.
The ZyXEL Device uses its current WAN IP address (static or dynamic) in setting
up the VPN tunnel if you leave this field as 0.0.0.0. If the WAN connection goes
down, the ZyXEL Device uses the dial backup IP address for the VPN tunnel
when using dial backup or the LAN IP address when using traffic redirect.
Otherwise, you can enter one of the dynamic domain names that you have
configured (in the DDNS screen) to have the ZyXEL Device use that dynamic
domain name's IP address.
The VPN tunnel has to be rebuilt if My IP Address changes after setup.
Local ID Type Select IP to identify this ZyXEL Device by its IP address.
Select DNS to identify this ZyXEL Device by a domain name.
Select E-mail to identify this ZyXEL Device by an e-mail address.
Local Content When you select IP in the Local ID Type field, type the IP address of your
computer in the Local Content field. The ZyXEL Device automatically uses the
IP address in the My IP Address field (refer to the My IP Address field
description) if you configure the Local Content field to 0.0.0.0 or leave it blank.
It is recommended that you type an IP address other than 0.0.0.0 in the Local
Content field or use the Domain Name or E-mail ID type in the following
situations.
• When there is a NAT router between the two IPSec routers.
• When you want the remote IPSec router to be able to distinguish between
VPN connection requests that come in from IPSec routers with dynamic WAN
IP addresses.
When you select Domain Name or E-mail in the Local ID Type field, type a
domain name or e-mail address by which to identify this ZyXEL Device in the
Local Content field. 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.
