DESCRIPTION
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.
Select Main or Aggressive from the drop-down list box. Multiple SAs connecting
through a secure gateway must have the same negotiation mode.
Select Tunnel mode or Transport mode from the drop-down list box.
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.
Specify the IP addresses of the devices behind the ZyXEL Device that can use
the VPN tunnel. The local IP addresses must correspond to the remote IPSec
router's configured remote IP addresses.
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.
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.
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.
When the Local Address Type field is configured to Range, enter the end
(static) IP address, in a range of computers on the LAN behind your ZyXEL
Device. When the Local Address Type field is configured to Subnet, this is a
subnet mask on the LAN behind your ZyXEL Device.
Specify the IP addresses of the devices behind the remote IPSec router that can
use the VPN tunnel. The remote IP addresses must correspond to the remote
IPSec router's configured local IP addresses.
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.
Use the drop-down menu to choose Single, Range, or Subnet. Select Single
with 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.
When the Remote Address Type field is configured to Single, enter a (static) IP
address on the network behind the remote IPSec router. When the Remote
Address Type field is configured to Range, enter the beginning (static) IP
address, in a range of computers on the network behind the remote IPSec router.
When the Remote Address Type field is configured to Subnet, enter a (static) IP
address on the network behind the remote IPSec router.
