Wireless Cable Modem Gateway CG814WG v3 Reference Manual
3-2 Content Filtering and Firewall Rules
v1.0, June 2007
Logs
A log is a detailed record of the Denial of Service (DoS) attacks directed at your network. You can
use e-mail notification to receive these logs in an e-mail message. If you do not have e-mail
notification set up you can connect to the gateway to view the logs.
To receive logs by e-mail:
1. For the Contact Email Address, type an e-mail address to which the logs will be sent. Use a
full e-mail address (for example, ChrisXY@myISP.com).
2. For the SMTP Server Name, type the outgoing SMTP mail server of your ISP (for example,
mail.myISP.com). If you leave this box blank, no alerts or logs will be sent.
3. Select the E-mail Alerts Enable check box.
4. Click Apply.
For information about event logs, see “Event Log” in Chapter 4.
Blocking Keywords, Sites, and Services
The gateway provides a variety of options for blocking Internet based content and
communications services. With its content filtering feature, the CG814WG v3 Gateway
prevents objectionable content from reaching your PCs. The CG814WG v3 allows you to control
access to Internet content by screening for keywords within Web addresses.
It also has the
capability to block access to all sites except those that are explicitly allowed. Key content
filtering options include:
• Blocking access from your LAN to Internet locations that contain keywords that your specify.
• Blocking access to websites that you specify as off-limits.
• Allowing access to only websites that you specify as allowed.
