device. After a netfilter rule is created, the open access to the system is disabled and all
incoming data packets are compared to the netfilter rules.

1. Turn on the matrix switch and wait until the device is ready for operation.

IMPORTANT:
Now open access to the system is enabled.
3. Use the Config Panel web application to edit the netfilter rules that are stored in
the appliance and save these rules.
IMPORTANT:
The former settings are reactivated if you do not create any new
netfilter rules within 15 minutes.
