	User Defined - this virtual server supports a specific IP address, specified in the
	User Defined field.
	HOST address - the drop-down box lists all the HOST address objects in the
	ZyWALL. If you select one of them, this virtual server supports the IP address
	specified by the address object.
	Select Create Object to configure a new IP address object.
User Defined	This field is available if Original IP is User Defined. Type the destination IP
Original IP	address that this virtual server supports.
Mapped IP	Use the drop-down list box to indicate to which translated destination IP address
	this virtual server forwards the packet. Choices are:
	User Defined - this virtual server supports a specific IP address, specified in the
	User Defined field.
	HOST address - the drop-down box lists all the HOST address objects in the
	ZyWALL. If you select one of them, this virtual server supports the IP address
	specified by the address object.
	Select Create Object to configure a new IP address object.
User Defined	This field is available if Mapped IP is User Defined. Type the translated destination
Original IP	IP address that this virtual server supports.
Port Mapping	Use the drop-down list box to select how many original destination ports this virtual
Type	server supports for the selected destination IP address (Original IP). Choices are:
	Any - this virtual server supports all the destination ports.
	Port - this virtual server supports one destination port.
	Ports - this virtual server supports a range of destination ports. You might use a
	range of destination ports for unknown services or when one server supports more
	than one service.
	See Appendix B on page 815 for some common port numbers.
Protocol Type	This field is available if Mapping Type is Port or Ports. Select the protocol (TCP,
	UDP, or Any) used by the service requesting the connection.
Original Port	This field is available if Mapping Type is Port. Enter the original destination port
	this virtual server supports.
Mapped Port	This field is available if Mapping Type is Port. Enter the translated destination port
	if this virtual server forwards the packet.
Original Start	This field is available if Mapping Type is Ports. Enter the beginning of the range of
Port	original destination ports this virtual server supports.
Original End Port	This field is available if Mapping Type is Ports. Enter the end of the range of
	original destination ports this virtual server supports.
Mapped Start	This field is available if Mapping Type is Ports. Enter the beginning of the range of
Port	translated destination ports if this virtual server forwards the packet.
Mapped End	This field is available if Mapping Type is Ports. Enter the end of the range of
Port	translated destination ports if this virtual server forwards the packet. The original
	port range and the mapped port range must be the same size.
Add	If the server will initiate sessions to the clients, select this check box to create a
corresponding	corresponding policy route so the ZyWALL uses the same public IP address as the
Policy Route rule	traffic’s source address. This is called NAT 1:1.
for NAT 1:1	Or you can click Policy Route to go to the screens where you can manually
mapping.	configure a NAT 1:1 policy route for this virtual server.
	See NAT 1:1 Example on page 313 for an example of NAT 1:1.
