Each NAT Protocol map entry will time-out if there is no traffic of that
protocol for the specified number of minutes. For example, UDP entries
time-out if there is no UDP traffic after 6 (default) minutes.

Description
This feature allows you to:
* Direct your Gateway to forward all externally initiated IP traffic (TCP
and UDP protocols only) to a default host on the LAN.
* Enable it for certain situations:
– Where you cannot anticipate what port number or packet
protocol an in-bound application might use. For example, some
network games select arbitrary port numbers when a connection
is opened.
– When you want all unsolicited traffic to go to a specific LAN host.
