To access this dialog box, select Global/NAT Configuration from the Device View.
NAT allows internal networks which use private IP addresses to be translated into a valid external “global” IP address (or addresses). (See RFC 1918 "Address Allocation for Private Internets" for more information about private IP addresses.) This can allow a private network to provide Internet access through a single "official" IP address. It can also function as a minimal fire- wall by limiting access to the internal network from external networks while allowing the internal network easy access to the Internet.
