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 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.
UPnP and ZyXEL

Internet Gateway Device (IGD) 1.0.
See Section 7.8 on page 158 for examples of installing and using UPnP.

Workgroup name
This is the name given to a set of computers that are connected on a network and

workgroup name when you set up a network.
Shares

is given a folder, called a “share”. If a USB hard drive connected to the ZyXEL
Device has more than one partition, then each partition will be allocated a share.
You can also configure a “share” to be a sub-folder or file on the USB device.
