Device Management

Use the Web Configurator to easily configure the rich range of features

 

on the NBG-417N.

 

 

Wireless Functionality

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

 

to the NBG-417N wirelessly. Enable wireless security ( WPA(2)-PSK)

 

and/or MAC filtering to protect your wireless network.

 

Note: The NBG-417N 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 to put it on the NBG-417N.

 

Note: Only upload firmware for your specific model!

 

 

Configuration Backup &

Make a copy of the NBG-417N’s configuration and put it back on the

Restoration

NBG-417N later if you decide you want to revert back to an earlier

 

configuration.

 

 

Network Address

Each computer on your network must have its own unique IP address.

Translation (NAT)

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 NBG-417N 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 NBG-417N 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 NBG-417N 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 NBG-417N.

 

 

Wireless LAN Scheduler

You can schedule the times the Wireless LAN is enabled/disabled.

 

 

Time and Date

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

 

on your NBG-417N. 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

Use this feature to have the NBG-417N assign IP addresses, an IP

Configuration Protocol)

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.
