Disabling the netfilter rules temporarily
In the default status of the central module, all network computers have access to the
extender’s IP address (open system access).
The web application enables you to create netfilter rules to control the 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 Config Panel web applica-
tion, they can be can temporarily disabled in order to be edited.
How to disable the netfilter rules temporarily:
1. If necessary, switch on the central module and wait until the device is ready for
operation.
2. Press and hold the Reset button on the front panel of the device 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.
