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 ZyXEL Device 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 if you want to set up a VPN tunnel when there are NAT
routers between the ZyXEL Device and remote IPSec router. The remote IPSec
router must also enable NAT traversal, and the NAT routers have to forward UDP
port 500 packets to the remote 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 ZyXEL Device 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 ZyXEL Device assigns this additional DNS server to the ZyXEL Device'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.
Local
Local IP addresses must be static and correspond to the remote IPSec router's
configured remote IP addresses.
Two active SAs can have the same configured 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.
In order to have more than one active rule with the
Secure Gateway Address
field set to
0.0.0.0
, the ranges of the local IP addresses cannot overlap between
rules.
If you configure an active rule with
0.0.0.0
in the
Secure Gateway Address
field
and the LAN’s full IP address range as the local IP address, then you cannot
configure any other active rules with the
Secure Gateway Address
field set to
0.0.0.0
.
Local Address
Type
Use the drop-down menu to choose
Single
,
Range
, or
Subnet
. Select
Single
for
a single IP address. Select
Range
for a specific range of IP addresses. Select
Subnet
to specify IP addresses on a network by their subnet mask.
IP Address Start
When the
Local Address Type
field is configured to
Single
, enter a (static) IP
address on the LAN behind your ZyXEL Device. When the
Local Address Type
field is configured to
Range
, enter the beginning (static) IP address, in a range of
computers on your LAN behind your ZyXEL Device. When the
Local Address
Type
field is configured to
Subnet
, this is a (static) IP address on the LAN behind
your ZyXEL Device.
