NAT Configuration Dialog Box
NAT Configuration Dialog Box
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.
