Temporarily deactivating the netfilter rules
In the default status of the KVM extender, 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
extender. As soon as a netfilter rule has been created, the open access to the system
is deactivated and all incoming data packets are compared to the netfilter rules.
If the currently adjusted netfilter rules prevent the access to the web application,
they can be temporarily deactivated in order to be edited.
How to deactivate the netfilter rules temporarily:
1. Press and hold the Reset button on the front panel for five seconds.
2. Use the Config Panel web application to edit the netfilter rules stored in the device
and, afterwards, save these rules.
IMPORTANT: This activates the open system access.
IMPORTANT: The former settings are reactivated if no new netfilter rules are
created within 15 minutes.
