When there is outbound traffic but no inbound traffic, the SA times out

automatically after two minutes. A tunnel with no outbound or inbound

traffic is "idle" and does not timeout until the SA lifetime period expires.

5.20 UPnP Overview

Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for

simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a

network, obtain an IP address, convey its capabilities and learn about other devices on the network.

In turn, a device can leave a network smoothly and automatically when it is no longer in use.

All UPnP-enabled devices may communicate freely with each other without additional

configuration. Disable UPnP if this is not your intention.

Windows ME and Windows XP support UPnP. See the Microsoft website for information about

other Microsoft operating systems.
