Configuring Network Address Translation

The [NAT Configuration] page contains the following elements:

•The [NAT Options] drop-down list will provide access to the [NAT Configuration] page and [NAT Global Information] table (shown by default and in Figure 16), the [Network Address Translation (NAT) Rule Configuration] page (see Figure 18) and the [NAT Translations] page (see Figure 20).

•The [Enable] and [Disable] radio buttons will allow you to turn on or off the NAT feature.

•The [NAT Global Information] table will display the following settings that apply to all NAT rule translations:

Field	Description
TCP Idle Timeout	When two computers communicate via the Internet,
(sec):	a TCP-based communication session is created between them
TCP Close Wait	to control the exchange of data packets. The TCP session can
	be viewed as being in one of three states, depending on the
(sec):
	types of packets being transferred.
TCP Def Timeout
	- The establishing state, where the connection is being set up.
(sec):
	- The active state, where the connection is being used to
	transfer data.
	- The closing state, in which the connection is being shut down.
	When a NAT rule is effective on a TCP session in the active
	state, the session will timeout if no packets are received for
	the time specified in [TCP Idle Timeout].
	When in the closing state, the session will timeout if no packets
	are received for the time specified in [TCP Close Wait].
	When in the establishing state, the session will timeout
	if no packets are received for the time specified in [TCP
	Def Timeout].
UDP Timeout	Same as TCP Idle Timeout, but for UDP-based
(sec):	communication sessions.
ICMP Timeout	Same as TCP Idle Timeout, but for ICMP-based
(sec):	communication sessions.
