Table 84 Configuration > Network > NAT > Add

LABEL	DESCRIPTION
Create new Object	Use to configure any new settings objects that you need to use in this screen.
Enable Rule	Use this option to turn the NAT rule on or off.
Rule Name	Type in the name of the NAT rule. The name is used to refer to the NAT rule. You may
	use 1-31 alphanumeric characters, underscores(_), or dashes (-), but the first
	character cannot be a number. This value is case-sensitive.
Classification	Select what kind of NAT this rule is to perform.
	Virtual Server - This makes computers on a private network behind the ZyWALL
	available to a public network outside the ZyWALL (like the Internet).
	1:1 NAT - If the private network server will initiate sessions to the outside clients,
	select this to have the ZyWALL translate the source IP address of the server’s outgoing
	traffic to the same public IP address that the outside clients use to access the server.
	Many 1:1 NAT - If you have a range of private network servers that will initiate
	sessions to the outside clients and a range of public IP addresses, select this to have
	the ZyWALL translate the source IP address of each server’s outgoing traffic to the
	same one of the public IP addresses that the outside clients use to access the server.
	The private and public ranges must have the same number of IP addresses.
	One many 1:1 NAT rule works like multiple 1:1 NAT rules, but it eases configuration
	effort since you only create one rule.
