By disabling the firewall you endanger the security of your

firewall should only temporarily be disabled for testing purposes
such as troubleshooting.
The configuration of the firewall rules is divided into the following tabs:
■ Basic Configuration
– Here you will find predefined firewall rules which you can enable or disable.
■ User Configuration
– Here you can create, enable or disable your own firewall rules according to defined
specifications.
There is a ‘
Action’ column in both tabs. The firewall settings are applied with the [Apply]
button. There are the following setting options for the ‘Action’ column:
■ Accept
– The corresponding connection and connection request is accepted.
– The corresponding connection can be established.
■ Drop
– The corresponding connection is interrupted.
– There is no answer to the corresponding request.
– The corresponding package is discarded.
■ Reject
– The corresponding connection is rejected.
– The sender receives a response to the corresponding request.
■ Continue
– The rule is not executed.
– This can be used e.g., to skip a rule in the ‘Basic Configuration
’ and instead create
a rule in the ‘User Configuration’ and enable it there.
