the NBG-318S.

Wireless Functionality

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

the NBG-318S wirelessly. IEEE 802.11g clients can connect using the 

Super G function. Enable wireless security (WEP, WPA(2), WPA(2)-

PSK) and/or MAC filtering to protect your wireless network. 

Note: The NBG-318S 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.

Powerline Functionality

The HomePlug AV standard specifies how network devices 

communicate using standard electrical wiring. 
It supports a data transfer rate of up to 200Mbps. 
Data is encrypted using 128-bit AES (Advanced Encryption Standard). 
HomePlug AV compatible devices co-exist with HomePlug 1.0 devices 

but do not detect each other.
The range of a HomePlug AV network is 300 meters/984 feet in optimal 

conditions.
HomePlug AV is compatible with all OSs
Maximum number of powerline devices on a single network is 16.

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 NBG-

318S.

Note: Only upload firmware for your specific model!

Configuration Backup & 

Restoration

Make a copy of the NBG-318S’s configuration and put it back on the 

NBG-318S 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 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 NBG-318S 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-318S to check web sites against an external database.
