DESCRIPTION
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.
Local IP addresses must be static and 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.
Remote IP addresses must be static and 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
