N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 
Note:  If the Weekly, Daily, or Hourly option is selected and the log fills up \
before the specified period, the log is automatically emailed to the 
specified email address. After the log is sent, it is cleared from the 
wireless modem router’s memory. If the wireless modem router 
cannot email the log file, the log buffer might fill up. In this case, t\
he 
wireless modem router overwrites the log and discards its contents.
Log the Network Activity
A log is a detailed record of the websites that users on your network ha\
ve accessed or attempted to access. If you have set up content filtering on the Block S\
ites screen, the Logs 
screen shows you when someone on your network tried to access a blocked \
site. If you have 
email notification on, you will receive these logs in an email message. \
If you do not have 
email notification set up, you can view the logs on the Logs screen.
To log the network activity:
1.  Select  Content Filtering > Logs  to display the Logs screen:
Figure 31.  Logs screen
a.To delete all the log entries, click  Clear Log.
b.  To see the most recent access attempts, click  Refresh.
c.  To send the log file to your e-mail account, click  Send Log. This feature is useful for 
testing your e-mail settings.

2. 
Use the Include in Log check boxes to determine which events are include\
d in the log. 
Selecting all check boxes will increase the size of the log, so it is go\
od practice to disable 
any events that are not really required.
•     Attempted access to blocked sites. If selected, attempted Internet accesses that  were blocked are logged.
•     Connections to the Web-based interface of this Router . If selected, connections 
are logged to this router, rather than through this router to the Intern\
et.
•     Router operation. If selected, router operations not covered by the preceding  selections are logged.
•     Known DoS attacks and Port Scans . If selected, denial of service attacks, as well 
as port scans, are logged.
3.  The logs can be sent to a syslog server. Enable one of the three options\
 in the Syslog 
section, as required:
•     Disable. Select this if you do not have a syslog server.
•      Broadcast on LAN. The syslog data is broadcast rather than sent to a specific syslog 
server. Use this if your syslog server does not have a fixed IP address.\
•      Send to this Syslog server IP address . If your syslog server has a fixed IP address, 
select this option, and enter the IP address of your syslog server.
4.  Click  Apply to save your changes.
