Chapter 6 Device Security Settings
Vantage CNM User’s Guide

Active
Enable this feature to have the device use virtual (translated) IP
addresses for the local network for the VPN connection. You do not
configure the
Local Network
fields when you enable virtual address
mapping.
Virtual address mapping allows local and remote networks to have
overlapping IP addresses. Virtual address mapping (NAT over IPSec)
translates the source IP addresses of computers on your local
network to other (virtual) IP addresses before sending the packets to
the remote IPSec router. This translation hides the source IP
addresses of computers in the local network.
Mapping Type
Select
One-to-One
to translate a single (static) IP address on your
LAN to a single virtual IP address.
Select
Many-to-One
to translate a range of (static) IP addresses on
your LAN to a single virtual IP address. Many-to-one rules are for
traffic going out from your LAN, through the VPN tunnel, to the
remote network. Use port forwarding rules to allow incoming traffic
from the remote network.
Select
Many One-to-One
to translate a range of (static) IP
addresses on your LAN to a range of virtual IP addresses.
Virtual Address
Mapping Rule
If you are configuring a
Many-to-One
rule, click this button to go to
a screen where you can configure port forwarding for your VPN
tunnels. The VPN network policy port forwarding rules let the device
forward traffic coming in through the VPN tunnel to the appropriate IP
address.
Private Starting IP
Address
Specify the IP addresses of the devices behind the device that can
use the VPN tunnel.
When you select
One-to-One
in the
Type
field, enter the (static) IP
address of a computer on the LAN behind your device.
When you select
Many-to-One
or
Many One-to-One
in the
Type
field, enter the beginning (static) IP address in a range of computers
on the LAN behind your device.
Private Ending IP
Address
When you select
Many-to-One
or
Many One-to-One
in the
Type
field, enter the ending (static) IP address in a range of computers on
the LAN behind your device.
Virtual Starting IP
Address
Enter the (static) IP addresses that represent the translated private
IP addresses. These must correspond to the remote IPSec router's
configured remote IP addresses.
When you select
One-to-One
or
Many-to-One
in the
Type
field,
enter an IP address as the translated IP address. Many-to-one rules
are only for traffic going to the remote network. Use port forwarding
rules to allow incoming traffic from the remote network.
When you select
Many One-to-One
in the
Type
field, enter the
beginning IP address of a range of translated IP addresses.
