Nat Traversal Press [SPACE BAR] to choose either Yes or No. Choose Yes and press [ENTER] to
enable NAT traversal. NAT traversal allows you to set up a VPN connection when
there are NAT routers between the two IPSec routers.
The remote IPSec router must also have NAT traversal enabled. You can use NAT
traversal with ESP protocol using Transport or Tunnel mode, but not with AH
protocol nor with Manual key management.
In order for an IPSec router behind a NAT router to receive an initiating IPSec packet,
set the NAT router to forward UDP port 500 to the IPSec router behind the NAT
router.
Local ID type Press [SPACE BAR] to choose IP, DNS, or E-mail and press [ENTER].
Select IP to identify this Prestige by its IP address.
Select DNS to identify this Prestige by a domain name.
Select E-mail to identify this Prestige by an e-mail address.
Content When you select IP in the Local ID Type field, type the IP address of your computer
or leave the field blank to have the Prestige automatically use its own IP address.

characters) by which to identify this Prestige.
When you select E-mail in the Local ID Type field, type an e-mail address (up to 31
characters) by which to identify this Prestige.
The domain name or e-mail address that you use in the Content field is used for
identification purposes only and does not need to be a real domain name or e-mail
address.
My IP Addr Enter the IP address of your Prestige. The Prestige 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.
The VPN tunnel has to be rebuilt if this IP address changes.
Peer ID type Press [SPACE BAR] to choose IP, DNS, or E-mail and press [ENTER].

Content When you select IP in the Peer ID Type field, type the IP address of the computer
with which you will make the VPN connection or leave the field blank to have the
Prestige automatically use the address in the Secure Gateway Address field.

characters) by which to identify the remote IPSec router.
When you select E-mail in the Peer ID Type field, type an e-mail address (up to 31
characters) by which to identify the remote IPSec router.
The domain name or e-mail address that you use in the Content field is used for
identification purposes only and does not need to be a real domain name or e-mail
address. The domain name also does not have to match the remote router’s IP
address or what you configure in the Secure Gateway Address field below.
