Event Log
The Event Log page allows you to send firewall event log reporting to a standard SysLog
server or via email. Individual attack or configuration items can be selected that will be
sent to the SysLog server or emailed so that only the items of interest can be monitored.
Permitted connections, blocked connections, known Internet attack types, and Cable
Modem/Router configuration events can also be logged. The SysLog server must be on
the same subnet as the Private LAN behind the Cable Modem/Router (typically
192.168.0.x).
To access the
Event Log
page:
1
Click the
Router
menu tab.
2
Then click the
Firewall/Event Log
submenu.
Figure 23 shows an example of the menu and Table 25 describes the items you can
select.
