Reference Manual for the Model DG814 ADSL Modem Internet Gateway

Your outgoing mail server

Enter the name of your ISP’s outgoing (SMTP) mail server (such as mail.myISP.com). You may be able to find this information in the configuration menu of your e-mail program. If you leave this box blank, log and alert messages will not be sent via e-mail.

Send to this e-mail address

Enter the e-mail address to which logs and alerts are sent. This e-mail address will also be used as the From address. If you leave this box blank, log and alert messages will not be sent via e-mail.

You can specify that logs are automatically sent to the specified e-mail address with these options:

Send alert immediately

Check this box if you would like immediate notification of attempted access to a blocked site.

Send logs according to this schedule

Specifies how often to send the logs: Hourly, Daily, Weekly, or When Full.

Day for sending log

Specifies which day of the week to send the log. Relevant when the log is sent weekly or daily.

Time for sending log

Specifies the time of day to send the log. Relevant when the log is sent daily or weekly.

If the Weekly, Daily or Hourly option is selected and the log fills up before the specified period, the log is automatically e-mailed to the specified e-mail address. After the log is sent, the log is cleared from the gateway’s memory. If the gateway cannot e-mail the log file, the log buffer may fill up. In this case, the gateway overwrites the log and discards its contents.

The Model DG814 gateway uses the Network Time Protocol (NTP) to obtain the current time and date from one of several Network Time Servers on the Internet. In order to localize the time for your log entries, you must specify your Time Zone:

Time Zone

Select your local time zone. This setting will be used for the blocking schedule and for time-stamping log entries.

Daylight Savings Time

Check this box if your time zone is currently under daylight savings time.
