Table 16-7 VPN IKE
LABEL DESCRIPTION
IPSec Setup
Active Select this check box to activate this VPN policy. This option determines whether a
VPN rule is applied before a packet leaves the firewall.
Keep Alive
Select either
Yes
or
No
from the drop-down list box.
Select
Yes
to have the Prestige automatically reinitiate the SA after the SA lifetime
times out, even if there is no traffic. The remote IPSec router must also have keep
alive enabled in order for this feature to work.
NAT Traversal Select this check box 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.
Name Type up to 32 characters to identify this VPN policy. You may use any character,
including spaces, but the Prestige drops trailing spaces.
IPSec Key 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 if you
have problems using
IKE
key management.
Negotiation Mode
Select
Main
or
Aggressive
from the drop-down list box. Multiple SAs connecting
through a secure gateway must have the same negotiation mode.
Encapsulation Mode
Select
Tunnel
mode or
Transport
mode from the drop-down list box.
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.
