Configuring the LAN Channel and Name
1
Click the
Wireless Setup
link to open the Wireless menu, then click the
Channel and SSID
link to open the Channel and SSID screen:
2
Make the following changes to this screen as desired:
—
Wireless Channel: Use the default shown in most cases. You may need
to change the channel if neighbors have wireless routers, or if you lose
your connection while using certain remote telephones.
—
SSID
: Give your wireless LAN any name you desire. For best security, do
not use your name or address. The default SSID is
arris54g
.
— Broadcast SSID: Uncheck to prevent passers-by from seeing your
wireless LAN name in their connection utility. This provides only a small
amount of extra security, since many wireless utilities can learn an SSID
by listening to wireless traffic.
—
Protected Mode: Set to
On
only if needed to overcome interference.

Depending on the security mode chosen, the WTM552 displays one of the
following screens to allow you to configure a key.

Configuring the Firewall
The WTM552 provides a
firewall
to protect the computers on your home network
from unwanted access. The firewall provides the following features:
•
Virtual Server Support: if you have a server on your home network that you
want to make available to the general Internet, you can configure a virtual
server. The firewall passes requests from the Internet to the designated
computer on your home network.
•
DMZ: if you need to access a service that cannot pass through the firewall,
the DMZ allows a single computer on the home network to appear as if it
were connected directly to the Internet. A computer in the DMZ is complete-
ly exposed to the Internet as if there were no router or firewall, so it is best
to activate the DMZ only when necessary.
•
Client filters: you can use client filters to block computers on your network
from accessing the Internet (or certain services) during specific days and
times.
•
MAC Address filtering: allows access to the wireless network only by com-
puters specifically authorized to connect.
•
Ping blocking: ignores ICMP (Ping) requests from the Internet.
Proceed to the next page to begin configuring the firewall.
