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.

Time and Date

Get the current time and date from an external server when you turn on 

your NBG334W. You can also set the time manually. These dates and 

times are then used in logs.

Port Forwarding

If you have a server (mail or web server for example) on your network, 

then use this feature to let people access it from the Internet.

DHCP (Dynamic Host 

Configuration Protocol)

Use this feature to have the NBG334W 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.
