This screen provides you options on how you want to manage your system logs. The Wireless Router provides
four categories of event logging (Firewall, VPN, System, and ACL). You can configure the Wireless Router to send
the event log to you through e-mail, upload the log to syslog server, or view the log locally on the Wireless Router.

blocked) by the software firewall before an e-mail alert is sent. The minimum value is 20, the maximum value is

please check the
IPS Report
to know event details.
