LABEL	DESCRIPTION
Type	Choose the port mapping type from one of the following.
	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.
	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.
	Many-to-Many Overload: Many-to-Many Overload mode maps multiple
	local IP addresses to shared global IP addresses.
	Many-to-Many No Overload: Many-to-Many No Overload mode maps
	each local IP address to unique global IP addresses.
	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.

Local End IP	This is the end local IP address (ILA). If your rule is for all local IP
	addresses, then 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	This is the starting global IP address (IGA). Enter 0.0.0.0 here if you have
IP	a dynamic IP address from your ISP.
