DESCRIPTION
If there is a private DNS server that services the VPN, type its IP address here.
The Prestige assigns this additional DNS server to the Prestige's DHCP clients
that have IP addresses in this IPSec rule's range of local addresses. A DNS
server allows clients on the VPN to find other computers and servers on the VPN
by their (private) domain names.
The local IP address must be static and correspond to the remote IPSec router's
configured remote IP addresses.
Two active SAs can have the same local or remote IP address, but not both. You
can configure multiple SAs between the same local and remote IP addresses, as
long as only one is active at any time.
Remote IP addresses must be static and correspond to the remote IPSec router's
configured local IP addresses. The remote address fields do not apply when the
Secure Gateway Address field is configured to 0.0.0.0. In this case only the
remote IPSec router can initiate the VPN.
Two active SAs cannot have the local and remote IP address(es) both the same.
Two active SAs can have the same local or remote IP address, but not both. You
can configure multiple SAs between the same local and remote IP addresses, as
long as only one is active at any time.
Enter a (static) IP address on the network behind the remote IPSec router.
When the remote IP address is a single address, type it a second time here.
When the remote IP address is a range, enter the end (static) IP address, in a
range of computers on the network behind the remote IPSec router.
When the remote IP address is a subnet address, enter a subnet mask on the
network behind the remote IPSec router.
Enter the WAN 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.
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.
When you select IP in the Local ID Type field, type the IP address of your
computer in the local Content field. The Prestige 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 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 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 DNS or E-mail in the Local ID Type field, type a domain name
or e-mail address by which to identify this Prestige 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.
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 IPSec Keying Mode
field must be set to IKE). The remote address fields do not apply when the
Secure Gateway Address field is configured to 0.0.0.0. In this case only the
remote IPSec router can initiate the VPN.
