Local Log and Remote Log Web Pages (Fig. 36 and 37)
The gateway builds a log of firewall blocking actions that the Firewall has taken.
Using the Local Log page lets
you specify an email address to which you want the gateway to
email this log. You must also tell the gateway your outgoing (i.e. SMTP) email server’s name, so
it can direct the email to it. Enable Email Alerts has the gateway forward email notices when
Firewall protection events occur. Click
E-mail Log
to immediately send the email log. Click
Clear
Log
to clear the table of entries for a fresh start.
The log of these events is also visible on the screen. For each blocking event type that has taken
place since the table was last cleared, the table shows Description, Count, Last Occurrence, Target,
and Source.
The Remote Log page allows you to specify the IP address where a SysLog server is located and
select different types of firewall events that may occur. Then, each time such an event occurs,
notification is automatically sent to this log server.

Wireless Web Pages Group
Important: Changes to the wireless web pages should be made from a PC that is hard wired to the gateway.
The Wireless web pages group enables a variety of settings that can provide secure and reliable
wireless communications for even the most demanding tech-savvy user.
The DCW725 gateway offers a choice of 802.1X, WPA and WPA-PSK authentication of your PCs
to the gateway, 64 and 128 bit WEP encryption of communication between the gateway and your
PCs to guaranty privacy, and an Access Control List function that enables you to restrict wireless
access to only your specific PCs.
The wireless function will probably work in your home as shipped from the factory, but without
the security features activated. In addition, the factory default wireless channel setting may not
provide optimum performance in your home due to interference from other wireless devices.
Therefore, the following minimum changes are recommended from the factory defaults, to secure
your wireless communications and provide optimum performance.
Performance
Because your wireless communication travels through the air, the factory default wireless channel
setting may not provide optimum performance in your home if you or your neighbors have
other interfering 2.4 GHz devices such as cordless phones. If your wireless PC is experiencing very
sluggish or dramatically slower communication compared with the speed you achieve on your
PC that is wired to the gateway, try changing the channel number.
See the 802.11b/g Basic Web
Page discussion below for details.
Authentication
Authentication enables you to restrict your gateway from communicating with any remote
wireless PCs that aren’t yours. The following minimum authentication-related changes to factory
defaults are recommended. See the 802.11b/g Basic and Access Control Web Page discussions
below for details.
Network Name (SSID) – set to a unique name you choose
Network Type – set to
Open
Access Control List
- enter your wireless PCs' MAC addresses

Privacy
Privacy secures or scrambles messages traveling through the air between your wireless PCs and
the gateway, so they can't be observed by others. The following minimum privacy-related setting
changes to factory defaults are recommended. See the 802.11b/g Privacy Web Page discussion
below for details.
Data Encryption – set to WEP (64-bit)
PassPhrase – use this feature to generate security keys
802.11b/g Basic Web Page (Fig. 38)
Use this page to configure the wireless 802.11b/g channel in the 2.4 GHz band you want to use
and the SSID you will use. These must match the settings you make on your wireless-equipped PC
you want to be a part of your LAN.
The SSID is your Network Name. Change the factory default to a name of your choice up to 32
characters long. The wireless radio in your gateway can be completely de-activated by changing
Interface
to
Disabled
. Click the
Apply
button to save your settings.
The Network Type control is used to hide or reveal your network name to any remote, wireless
equipped PC in the area that may be scanning WiFi channels to find available WiFi networks. The
gateway WiFi radio frequently transmits a beacon signal which can contain this network name
(SSID). If you set Network Type to
Open
, your SSID is included in that beacon, and is therefore
detectable by any nearby wireless equipped PCs in the area. The benefit of using Open, is it can
speed your WiFi setup on some PCs. If you set Network Type to
Closed
, your SSID is not included
in the beacon. This hides your network name, but as a result may require a bit more effort on your
part to set up your wireless PCs.
Details of all settings on the 802.11b/g Basic Web Page are provided in Table 1.
