12.5 The UPnP Screen
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.
Use this screen to enable UPnP on the LTE3202-M430. Click Configuration > Remote Management > UPnP
to open the following screen.

12.5.1 Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and opening
firewall ports may present network security issues. Network information and configuration may also be
obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For security
reasons, the LTE3202-M430 allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.
