Device Management Use the Web Configurator to easily configure the rich range of features
on the NBG4615.
Wireless Functionality Allows IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n wireless
clients to connect to the NBG4615 wirelessly. Enable wireless security
(WPA(2)-PSK) and/or MAC filtering to protect your wireless network.
Note: The NBG4615 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 NBG4615.
Note: Only upload firmware for your specific model!
Configuration Backup &
Restoration
Make a copy of the NBG4615’s configuration and put it back on the
NBG4615 later if you decide you want to revert back to an earlier
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 NBG4615 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 NBG4615 blocks or allows access to web sites that you specify and
blocks access to web sites with URLs that contain keywords that you
specify.
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 traffic for example)
from a computer on a network (LAN or WAN for example) can access
the NBG4615.
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 NBG4615. 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 NBG4615 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.
