14. Configuring The Firewall
Revision 1.14.3 127 RX1000/RX1100™
The above figure shows the firewall menu prior to configuration.
Configure the firewall through the provided menus. The “Check Firewall” button can be selected after
each menu configuration to check the existing configuration and provide notice of items still to be
configured.
When the firewall is fully configured, the “Start Firewall” button may be selected. Starting the firewall
in this way will provide more detail (in the event of a problem). If the firewall starts cleanly, the menu
appearance will change to that of the figure below.
In order to start the firewall at each and every boot, you must enable it via the System folder, Bootup
And Shutdown menu.

The “Apply Configuration” button must be used after making configuration changes. It is recommended
that the “Check Firewall” button be used first to verify that any changes made are valid.
The “Refresh Configuration” button can be used to activate changes to the blacklisted host and traffic
shaping configurations.
The “Clear Configuration” button will remove the firewall rules completely and eliminate any
protection they offer. In some cases, you might wish to do this temporarily to determine if the firewall
is responsible for an application problem.
The “Stop Firewall” button will stop the firewall. Note that you should add an entry to the “When
Stopped” menu to allow access from your management station while the firewall is stopped. If
you do not do this, you lose web/ssh access and have to gain access via the console in order
to restart the firewall. Stopping the firewall will not disable it. Disable the firewall via the System
folder, Bootup And Shutdown menu.
The “Show Status” button presents a variety of information summarizing the status of the firewall and
routing system.
The “Check Firewall” button tests the current configuration to ensure it is valid.
