3. Refer to the following information as displayed within the Static Translation tab.

Type	Displays the NAT type as either:
	•	Inside - The set of networks that are subject to translation. These are the internal
		addresses you are trying to prevent from being exposed to the outside world.
	•	Outside - All other addresses. Usually these are valid addresses located on the Internet.
		Outside addresses pose no risk if exposed over a publicly accessible network.
Direction	Displays the Direction as either:
	•	Source - The inside network is transmitting data over the network its intended
		destination. On the way out, the source IP address is changed in the header and replaced
		by the (public) IP address.
	•	Destination - Packets passing through the NAT on the way back to the switch managed
		LAN are searched against to the records kept by the NAT engine. There the destination IP
		address is changed back to the specific internal private class IP address in order to reach
		the LAN over the switch managed network.
Protocol	Displays the tcp or udp option selected for use with the static translation.
Local Address	Displays the Local Address used at the local (source) end of the static NAT configuration.
	This address (once translated) will not be exposed to the outside world when the translation
	address is used to interact with the remote destination.
Local Port	Applies NAT on packets matching the specified port number. The port number matched can
	be either source or destination based on the direction specified. This option is valid only if
	the direction specified is destination.
Global Address	Modifies the IP address of the matching packet to the specified value. The IP address to be
	modified can be either source or destination based on the direction specified.
Global Port	Modifies the port number of the matching packet to the specified value. This option is valid
	only if the direction specified is destination.
