LABEL	DESCRIPTION
Local Network	Specify the IP addresses of the devices behind the ZyWALL 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.
Address Type	Use the drop-down list box to choose Single Address, Range Address, or
	Subnet Address. Select Single Address for a single IP address. Select Range
	Address for a specific range of IP addresses. Select Subnet Address to specify
	IP addresses on a network by their subnet mask.
Starting IP	When the Address Type field is configured to Single Address, enter a (static) IP
Address	address on the LAN behind your ZyWALL. When the Address Type field is
	configured to Range Address, enter the beginning (static) IP address, in a range
	of computers on the LAN behind your ZyWALL. When the Address Type field is
	configured to Subnet Address, this is a (static) IP address on the LAN behind
	your ZyWALL.
Ending IP	When the Address Type field is configured to Single Address, this field is N/A.
Address/Subnet	When the Address Type field is configured to Range Address, enter the end
Mask	(static) IP address, in a range of computers on the LAN behind your ZyWALL.
	When the Address Type field is configured to Subnet Address, this is a subnet
	mask on the LAN behind your ZyWALL.
Remote Network	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.
Address Type	Use the drop-down list box to choose Single Address, Range Address, or
	Subnet Address. Select Single Address with a single IP address. Select Range
	Address for a specific range of IP addresses. Select Subnet Address to specify
	IP addresses on a network by their subnet mask.
Starting IP	When the Address Type field is configured to Single Address, enter a (static) IP
Address	address on the network behind the remote IPSec router. When the Addr Type field

	range of computers on the network behind the remote IPSec router. When the
	Address Type field is configured to Subnet Address, enter a (static) IP address
	on the network behind the remote IPSec router.
Ending IP	When the Address Type field is configured to Single Address, this field is N/A.
Address/Subnet	When the Address Type field is configured to Range Address, enter the end
Mask	(static) IP address, in a range of computers on the network behind the remote
	IPSec router. When the Address Type field is configured to Subnet Address,

Gateway Policy
Information
My ZyWALL	When the ZyWALL is in router mode, enter the WAN IP address of your ZyWALL
	or leave the field set to 0.0.0.0.
	The ZyWALL uses its current WAN IP address (static or dynamic) in setting up the
	VPN tunnel if you leave this field as 0.0.0.0. If the WAN connection goes down, the
	ZyWALL uses the dial backup IP address for the VPN tunnel when using dial
	backup or the LAN IP address when using traffic redirect.
	The VPN tunnel has to be rebuilt if this IP address changes.
	When the ZyWALL is in bridge mode, this field is read-only and displays the
	ZyWALL’s IP address.
