Device Management

Use the web configurator to easily configure the rich range of features on

the NBG334W.

Wireless Functionality

Allows IEEE 802.11b and/or IEEE 802.11g wireless clients to connect to

the NBG334W wirelessly. Enable wireless security (WEP, WPA(2),

WPA(2)-PSK) and/or MAC filtering to protect your wireless network.

Note: The NBG334W may be prone to RF (Radio

Frequency) interference from other 2.4 GHz devices

such as microwave ovens, wireless phones,

Bluetooth enabled devices, and other wireless LANs.

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

NBG334W.

Note: Only upload firmware for your specific model!

Configuration Backup &

Restoration

Make a copy of the NBG334W’s configuration and put it back on the

NBG334W later if you decide you want 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 a single public IP address to multiple private IP

addresses for the computers on your network.

Firewall

You can configure firewall on the NBG334W 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 NBG334W 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 NBG334W 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.
