LABEL	DESCRIPTION
NAT Traversal	This function is available if the VPN protocol is ESP.
	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	Select Tunnel mode or Transport mode from the drop-down list box.
Mode
DNS Server (for	If there is a private DNS server that services the VPN, type its IP address here.
IPSec VPN)	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	Use the drop-down menu to choose Single, Range, or Subnet. Select Single for
Type	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.
End / Subnet Mask	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.
