Device Management Use the web configurator to easily configure the rich range of features on
the ZyXEL Device.
Wireless Functionality Allow the IEEE 802.11b and/or IEEE 802.11g wireless clients to connect to
the ZyXEL Device wirelessly. Enable wireless security (WEP, WPA(2),
WPA(2)-PSK) and/or MAC filtering to protect your wireless network.
Firmware Upgrade Download new firmware (when available) from the ZyXEL web site and use
the web configurator, an FTP or a TFTP tool to put it on the ZyXEL Device.
Note: Only upload firmware for your specific model!
Configuration Backup &
Restoration
Make a copy of the ZyXEL Device’s configuration. You can put it back on
the ZyXEL Device later if you decide to revert back to an earl i er
configuration.
Network Address
Translation (NAT)
Each computer on your network must have its own unique IP address. Use
NAT to convert your public IP address(es) to multiple private IP addresses
for the computers on your network.
Port Forwarding If you have a server (mail or web server for example) on your network, you
can use this feature to let people access it from the Internet.
DHCP (Dynamic Host
Configuration Protocol)
Use this feature to have the ZyXEL Device assign IP addresses, an IP
default gateway and DNS servers to computers on your network.
Dynamic DNS Support With Dynamic DNS (Domain Name System) support, you can use a fixed
URL, www.zyxel.com for example, with a dynamic IP address. You must
register for this service with a Dynamic DNS service provider.
IP Multicast IP multicast is used to send traffic to a specific group of computers. The
ZyXEL Device supports versions 1 and 2 of IGMP (Internet Group
Management Protocol) used to join multicast groups (see RFC 2236).
Time and Date Get the current time and date from an external server when you turn on
your ZyXEL Device. You can also set the time manually. These dates and
times are then used in logs.
Logs Use logs for troubleshooting. You can send logs from the ZyXEL Device to
an external syslog server.
Universal Plug and Play
(UPnP)
A UPnP-enabled device can dynamically join a network, obtain an IP
address and convey its capabilities to other devices on the network.
Firewall You can configure firewall on the ZyXEL Device for secure Internet access.
When the firewall is on, by default, all incoming traffic from the Internet to
your network is blocked unless it is initiated from your network. This means
that probes from the outside to your network are not allowed, but you can
safely browse the Internet and download files for example.
Content Filter The ZyXEL Device blocks or allows access to web sites that you specify
and blocks access to web sites with URLs that contain keywords that you
specify. You can define time periods and days during which content filtering
is enabled. You can also include or exclude particular computers on your
network from content filtering.
You can also subscribe to category-based content filtering that allows your
ZyXEL Device to check web sites against an external database.
Bandwidth Management You can efficiently manage traffic on your network by reserving bandwidth
and giving priority to certain types of traffic and/or to particular computers.
Remote Management This allows you to decide whether a service (HTTP or FTP traffic for
example) from a computer on a network (LAN or WAN for example) can
access the ZyXEL Device.
