Logging and Alerts Page 31
Configure the following settings:
1. Mail Server - To e-mail log or alert messages, enter the name or IP address of your mail
server in the Mail Server field. If this field is left blank, log and alert messages are not
e-mailed.
2. Send Log To - Enter your full e-mail address(username@mydomain.com) in the Send log
to field to receive the event log via e-mail. Once sent, the log is cleared from the SonicWALL
memory. If this field is left blank, the log is not e-mailed.
3. Send Alerts To - Enter your full e-mail address (username@mydomain.com) in the Send
alerts to field to be immediately e-mailed when attacks or system errors occur. Enter a
standard e-mail address or an e-mail paging service. If this field is left blank, alert
messages are not e-mailed.
4. Firewall Name - The Firewall Name appears in the subject of e-mails sent by the
SonicWALL. The Firewall Name is helpful if you are managing multiple SonicWALLs
because it specifies the individual SonicWALL sending a log or an alert e-mail. By default,
the
Firewall Name is set to the SonicWALL serial number.
5. Syslog Server - In addition to the standard event log, the SonicWALL can send a detailed
log to an external Syslog server. Syslog is an industry-standard protocol used to capture
information about network activity. The SonicWALL Syslog captures all log activity and
includes every connection source and destination IP address, IP service, and number of
bytes transferred. The SonicWALL
Syslog support requires an external server running a
Syslog daemon on UDP Port 514.
Syslog Analyzers such as WebTrends Firewall Suite can be used to sort, analyze, and graph
the
Syslog data.
Enter the Syslog server name or IP address in the Syslog Server 1 or Syslog Server 2
field. Messages from the SonicWALL are then sent to the servers. If the SonicWALL is
managed by SGMS, however, the
Syslog Server fields cannot be configured by the
administrator of the SonicWALL.
6. E-mail Log Now - Clicking E-mail Log Now immediately sends the log to the address in
the Send Log To field and then clears the log.
7. Clear Log Now - Clicking Clear Log Now deletes the contents of the log.
8. Send Log / Every / At - The Send Log menu determines the frequency of log e-mail
messages: Daily , Weekly , or When Full . If the Weekly option is selected, then enter
the day of the week the e-mail is sent in the Every menu. If the Weekly or the Daily
option is selected, enter the time of day when the e-mail is sent in the At field. If the When
Full option is selected and the log fills up, it is e-mailed automatically.
9. When log overflows - The log buffer fills up if the SonicWALL cannot e-mail the log file.
The default behavior is to overwrite the log and discard its contents. However, you can
configure the SonicWALL to shut down and prevent traffic from traveling through the
SonicWALL if the log is full.
