	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),

		addresses to shared global IP addresses.
		4. Many One-to-One: Many One-to-one 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.
