3Select to search the messages in the selected log.

4Select AND to search for messages that match all the specified search criteria.

5Select OR to search for messages that match one or more of the specified search criteria.

6Select one or more of the following search criteria:

Keyword	To search for any text in a log message. Keyword searching is
	case-sensitive.
Time	To search log messages created during the selected year, month, day, and
	hour.

7Select OK to run the search.

The web-based manager displays the messages that match the search criteria. You can scroll through the messages or run another search.

Note: After running a search, to display all log messages again, run another search but leave all the search fields blank.

Configuring alert email

You can configure the FortiGate unit to send alert email to up to three email addresses when there are virus incidents, block incidents, network intrusions, and other firewall or VPN events or violations. After you set up the email addresses, you can test the settings by sending test email.

•Adding alert email addresses

•Testing alert email

•Enabling alert email

Adding alert email addresses

Because the FortiGate unit uses the SMTP server name to connect to the mail server, it must be able to look up this name on your DNS server. Therefore, before configuring alert email ensure that you have configured at least one DNS server.

To add a DNS server

1Go to System > Network > DNS.

2If they have not already been added, add the primary and secondary DNS server addresses provided to you by your ISP.

3Select Apply.

To add alert email addresses

1Go to Log&Report > Alert Mail > Configuration.

2Select Authentication if your email server requires an SMTP password.
