DESCRIPTION
Click this to create a new rule.
This is the index number of the address mapping set.
This is the starting Inside Local IP Address (ILA).
This is the ending Inside Local IP Address (ILA). This field is blank for One-to-One mapping
types.
This is the address mapping type.
One-to-One: This mode 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.
Many-to-One: This mode maps multiple local IP addresses to one global IP address. This is
equivalent to SUA (that is, PAT, port address translation), the Device's Single User Account
feature that previous routers supported only.
Click the Edit icon to go to the screen where you can edit the address mapping rule.
Click the Delete icon to delete an existing address mapping rule. Note that subsequent
address mapping rules move up by one when you take this action.
