4-36 Firewall Protection and Content Filtering
v1.0, January 2010
E-Mail Notifications of Event Logs and Alerts
The firewall logs can be configured to log and then e-mail denial of access, general attack
information, and other information to a specified e-mail address. For example, your VPN firewall
will log security-related events such as: accepted and dropped packets on different segments of
your LAN; denied incoming and outgoing service requests; hacker probes and login attempts; and
other general information based on the settings that you enter on the Firewall Logs & E-mail
screen. In addition, if you have set up content filtering on the Block Sites screen (see “Blocking
Internet Sites (Content Filtering)” on page 4-26), a log will be generated when someone on your
network tries to access a blocked site.
To configure e-mail or syslog notification, or to view the logs, see “Activating Notification of
Events and Alerts” on page 6-23.
Administrator Tips
Consider the following operational items:
• As an option, you can enable remote management if you have to manage distant sites from a
central location (see “Enabling Remote Management Access” on page 6-14).
• Although setting firewall rules (see “Using Rules to Block or Allow Specific Kinds of Traffic”
on page 4-2) is the basic way of managing the traffic through your system, you can further
refine your control with the following features of the VPN firewall:
– Groups and hosts (see “Managing Groups and Hosts” on page 3-6)
– Services (see “Services-Based Rules” on page 4-2)
– Schedules (see “Setting a Schedule to Block or Allow Specific Traffic” on page 4-25)
– Block sites (see “Blocking Internet Sites (Content Filtering)” on page 4-26)
– Source MAC filtering (see “Configuring Source MAC Filtering” on page 4-29)
– Port triggering (see “Configuring Port Triggering” on page 4-33)
