	Table 6-7 Address Mapping Rule Edit
LABEL	DESCRIPTION
Type	Choose the port mapping type from one of the following.
	1. One-to-One: One-to-One mode maps one local IP address to one global IP
	address. Note that port numbers do not change for One-to-one NAT mapping type.
	2. Many-to-One: Many-to-One mode maps multiple local IP addresses to one global
	IP address. This is equivalent to SUA (i.e., PAT, port address translation), ZyXEL's
	Single User Account feature that previous ZyXEL routers supported only.
	3. Many-to-Many Overload: Many-to-Many Overload mode maps multiple local IP
	addresses to shared global IP addresses.
	4. Many-to-Many No Overload: Many-to-Many No Overload mode maps each local
	IP address to unique global IP addresses.
	5. Server: This type allows you to specify inside servers of different services behind
	the NAT to be accessible to the outside world.
Local Start IP	This is the starting local IP address (ILA). Local IP addresses are N/A for Server port
	mapping.

	enter 0.0.0.0 as the Local Start IP address and 255.255.255.255 as the Local End
	IP address.
	This field is N/A for One-to-Oneand Server mapping types.
Global Start IP	This is the starting global IP address (IGA). Enter 0.0.0.0 here if you have a dynamic
	IP address from your ISP.
