Configuring Network Address Translation

For each current NAT Translations session, the table contains the following fields:

Field	Description
Trans Index	This is the sequential number assigned to the IP session used
	by this NAT translation session.
Rule ID	This field indicates the ID of the invoked NAT rule.
Interface	This field indicates the device interface on which the NAT rule
	was invoked (from the rule definition).
Protocol	This field indicates the IP protocol used by the data packets that
	are undergoing translations (from the rule definition) Example:
	[TCP], [UDP], [ICMP].
Alg Type	This is the Application Level Gateway (ALG), if any, that was
	used to enable this NAT translation (ALGs are special settings
	that certain applications require in order to work while NAT
	is enabled).
NAT Direction	This field indicates the direction ([Inside] or [Outside]) of the
	translation. A NAT direction is assigned to each port; the
	Ethernet and USB ports are defined as [Inside] ports, and the
	WAN ports are defined as [Outside] ports. The NAT direction
	is determined by the interface on which the rule is invoked.
Entry Age	This field indicates the elapsed time, in seconds, of the NAT
	translation session.

You can click in the [Action] column to view additional details about a NAT translation session.
