Wireless Functionality
(wireless devices only)

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

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

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.

QoS

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.

Any IP

The Any IP feature allows a computer to access the Internet and the ZyXEL

Device without changing the network settings (such as IP address and

subnet mask) of the computer, when the IP addresses of the computer and

the ZyXEL Device are not in the same subnet.
