15.3 Configuring Log Settings
To change your ZyWALL’s log settings, click LOGS , then the Log Settings tab. The screen
appears as shown.
Use the Log Settings screen to configure to where the ZyWALL is to send logs; the schedule
for when the ZyWALL is to send the logs and which logs and/or immediate alerts the
ZyWALL is to send.
An alert is a type of log that warrants more serious attention. They include system errors,
attacks (access control) and attempted access to blocked web sites or web sites with restricted
web features such as cookies, active X and so on. Some categories such as
System Errors
consist of both logs and alerts. You may differentiate them by their color in the View Log
screen. Alerts display in red and logs display in black.
Note: Alerts are e-mailed as soon as they happen. Logs may be e-mailed as soon as
the log is full (see
Log Schedule ). Selecting many alert and/or log categories
(especially Access Control ) may result in many e-mails being sent.

Protocol packet. “W to W/ZW” indicates that the packet was traveling from the WAN to the
WAN or the ZyWALL.
