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
Zyxel has achieved UPnP certification from the Universal Plug and Play Forum UPnP™ Implementers
Corp. (UIC).
See
Section on page 142
for examples on installing and using UPnP.
10.1.3 Before You Begin
Find out the MAC addresses of your network devices if you intend to add them to the DHCP Client List
screen.
10.2 LAN Setup
A LAN IP address is the IP address of a networking device in the LAN. You can use the Zyxel Device's LAN
IP address to access its Web Configurator from the LAN. The DHCP server settings define the rules on
assigning IP addresses to LAN clients on your network.
Use this screen to set the Local Area Network IP address and subnet mask of your Zyxel Device.
Configure DHCP settings to have the Zyxel Device or a DHCP server assign IP addresses to devices. Click
Network Setting
>
Home Networking
to open the
LAN Setup
screen.
Follow these steps to configure your LAN settings.
1
Enter an IP address into the
IP Address
field. The IP address must be in dotted decimal notation. This will
become the IP address of your Zyxel Device.
2
Enter the IP subnet mask into the
IP Subnet Mask
field. Unless instructed otherwise it is best to leave this
alone, the configurator will automatically compute a subnet mask based upon the IP address you
entered.
