5.7.4 Enabling Firewall
Before enabling the firewall, you must have Security enabled and you must have at least 1
internal interface or 1 external interface configured. Be sure that the WAN and/or LAN
connection and the Security Interfaces are defined and configured.
To enable the Firewall go to the Security State section and select Firewall Enabled. Click on
Change State to update the Security State section. The Firewall is now enabled on the
CopperJet.
Important: Enabling the Firewall will block ALL traffic going in and out of the
CopperJet. Firewall Policies need to be configured for allowing traffic
to pass through.
5.7.5 Enabling Intrusion Detection
Before enabling Intrusion Detection, you must have Security enabled and you must have
at least 1 internal interface or 1 external interface configured. Be sure that the WAN
and/or LAN connections and the Security Interfaces are defined and configured.
To enable Intrusion Detection, go to the Security State section and select Intrusion
Detection Enabled. Click on Change State to update the Security State section. The
Intrusion Detection is now enabled on the CopperJet.
5.7.6 Set a Security level
When you have enabled the firewall, you can set a Security Level.
Select a Security Level and click on Change State.
The high, medium, low and default levels contain default policy and port filter
configurations for each of your network interface connections, so you do not need to set
your own individual policies and port filters. If you explicitly set the level to none, all traffic
is blocked.
By default, no security level is set in your default configuration.
Setting a Firewall default security level automatically clears all previous Firewall settings.
5.7.7 Configuring portfilters
A portfilter is an individual rule that determines what kind of traffic can pass between two
interfaces specified in an existing policy.
To configure a portfilter:
From the Current Firewall Policies table, click on the Port Filters link for the policy that you
want to configure. The page displayed contains three Add Filter hyperlinks that allow you
to create three different kinds of portfilter:
