Chapter 15 VPN Screens

IPSec Keying Mode Select IKE or Manual from the drop-down list box. IKE provides more protection

so it is generally recommended. Manual is a useful option for troubleshooting.

Local Address

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 Address

Start

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.

Remote Address

End/Mask

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.

DNS Server (for

IPSec VPN)

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.

My IP Address

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.

Local ID Type

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.

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 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.
