Wireless Functionality Allows IEEE 802.11b and/or IEEE 802.11g wireless clients to
connect to the NBG4115 wirelessly. Enable wireless security (
WPA(2)-PSK) and/or MAC filtering to protect your wireless

such as microwave ovens, wireless phones,
Bluetooth enabled devices, and other wireless LANs.

Configuration Backup &
Restoration Make a copy of the NBG4115 ’ s configuration and put it back on
the NBG4115 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 NBG4115 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 NBG4115 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 NBG4115 to check web sites against an external
database.
