Firewall
The Firewall Configuration page allows setting up a firewall and configuring the security level.
A Firewall is a security service configured by the QX1000 administrator based on various criteria. The firewall allows or blocks traffic based on
policies, services and/or IP addresses. The firewall has several levels of security policies (low, medium or high). The administrator may add
additional service-based rules. Filtering rules will take effect only if the Firewall has been enabled and are independent from the selected firewall
security level.
The Firewall Configuration page offers the following components:
The Enable Firewall checkbox selection enables the firewall
security service. The firewall security level has to be selected,
otherwise the firewall cannot be enabled.
The Firewall Security radio buttons are the following:
•
Low Security - Everything that is not explicitly forbidden
will be allowed. This security level doesn't block anything
by default. It is recommended if the device is already
located behind another firewall or if every filter has been
configured correctly.
•
Medium Security - Traffic originating from the LAN side
may pass and traffic from the WAN side will be blocked by
default. This is the recommended security level.
•
High Security - Everything that is not explicitly allowed will
be blocked, including traffic from the LAN side.
The Advanced Firewall Settings link refers to the page where
QX1000’s privacy can be configured.
The View Filtering Rules link opens the Filtering Rules page.
