		Prestige 334 User’s Guide
Table 25	Address Mapping
LABEL		DESCRIPTION
Type		1. One-to-Onemode maps one local IP address to one global IP address. Note that
		port numbers do not change for the One-to-one NAT mapping type.
		2. Many-to-Onemode 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 mode maps multiple local IP addresses to shared global
		IP addresses.
		4. Many One-to-Onemode maps each local IP address to unique global IP
		addresses.
		5. Server allows you to specify inside servers of different services behind the NAT to
		be accessible to the outside world.
