DESCRIPTION
Select IKE or Manual from the drop-down list box. Manual is a useful
option for troubleshooting if you have problems using IKE key
management.
Type a number (base 10) from 1 to 999999 for the Security Parameter
Index.
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 Single, this field
is N/A. 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 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.
