SMCD3GN2 Wireless Cable Modem Gateway Administrator Manual
By default, the Gateway is configured to apply schedule rules to URL blocking 24 hours
every day. To change these settings:
1. To change the days when schedule rules are applied to URL blocking, uncheck Every Day
under Week Day. Then check the days when you want to apply schedule rules to URL
blocking.
2. To change the hours when schedule rules are applied to URL blocking, uncheck All Day.
Then specify the start and end times when you want to apply schedule rules to URL
blocking. Select AM or PM, where AM refers to times from Midnight to Noon and PM refers
to times from Noon to Midnight.
3. Click Apply.
Configuring Email and Syslog Alerts
The Gateway inspects packets at the application layer, and stores TCP and UDP session
information, including timeouts and number of active sessions. This information is helpful
when detecting and preventing Denial of Service (DoS) and other network attacks.
If you enabled the Gateway’s firewall or content-filtering feature, you can use the
Email/Syslog Alert menu to configure the Gateway to send email notifications or add entries
to the syslog when:
y Traffic is blocked
y Attempts are made to intrude onto the network
y Local computers try to access block URLs
You can configure the Gateway to generate email notifications or syslog entries immediately
or at a preconfigured time.
