Chapter 14 Universal Plug-and-Play (UPnP)
P-870HW-51a v2 User’s Guide
132
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the ZyXEL Device 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.
