MWR222 User's Guide
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.
You can configure firewall on the MWR222 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.
The MWR222 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 MWR222 to check web sites against an external
database.
You can efficiently manage traffic on your network by
reserving bandwidth and giving priority to certain types of
traffic and/or to particular computers.
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 MWR222.
You can schedule the times the Wireless LAN is
enabled/disabled.
Get the current time and date from an external server when
you turn on your MWR222. You can also set the time
manually. These dates and times are then used in logs.
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.
Use this feature to have the MWR222 assign IP addresses, an
IP default gateway and DNS servers to computers on your
network.
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.
