Disabling netfilter rules temporarily
In the device’s default status, all network computers have access to the device’s IP
address (open system access).
The web application enables you to create netfilter rules to control access to the
device. If a netfilter rule is created, the open access to the system is disabled and all
incoming data packets are compared to the netfilter rules.
If the currently adjusted netfilter rules prevent access to the web application, they
can be can temporarily disabled in order to be edited.
How to disable netfilter rules temporarily:
1. If necessary, switch on the device and wait until the it is ready for operation.
2. Press and hold the Reset button on the device’s front panel for 5 seconds.
3. Use the Config Panel web application to edit the netfilter rules that are stored in
the appliance and, afterwards, save these rules.
IMPORTANT: Now the open system access is enabled.
IMPORTANT: The former settings are reactivated if no new netfilter rules are
created within 15 minutes.
