The Firewall screen allows you to enable the advanced firewall functions of the
Gateway, so it can use Stateful Packet Inspection (SPI) to automatically detect
and block Denial of Service (DoS) and hacker attacks. Also, you can enable the
Gateway to maintain a security log, which can be viewed by clicking the Show
Firewall Log Table button. The security log can also be e-mailed to a specific
address, whose information should be entered in the Address Info setting.
• Firewall Service Enable or disable the advanced firewall functions.
• Address Info You can specify that the security log be e-mailed to a specific
address by completing the Mail Server, Mail Subject, Email Alert To, and
Return Address fields.
• Log Timer Depending on how often you want the security log e-mailed,
complete the Log Schedule, Day for Sending Alerts, and/or Time for Sending
Alerts fields.
Click the Show Firewall Log Table button to view the security log.
