Firewall Settings
A firewall protects an instrument by preventing unauthorized users from gaining access
to it through a network. In the default configuration of the R&S
ZNA, the firewall is
enabled. A remote desktop connection does not require any changes in the firewall
settings.
Administrator account
You need administrator rights to change the firewall settings. See note on
accounts and password protection"
Some actions require a different firewall configuration, e.g.:
●
To transfer data with other hosts in the LAN, you have to allow "File and Printer
Sharing".
To change the firewall settings, proceed as follows:
1. Access the operating system by pressing the Windows
®
key on the external key-
board. Open the "Control Panel".
2. Select "Windows Defender Firewall"
● Select "Allow an app or feature through Windows Defender Firewall" to enable
"File and Printer Sharing".
● Select "Turn Windows Firewall on or off" to enable or disable the firewall.
You must confirm a user account control message to allow the desired changes (see
). For detailed information about the firewall refer to the Windows
®
Help.
Risks of changing the firewall settings
Disabling the firewall or allowing exceptions may make your instrument more vulnera-
ble to viruses and intruders. It is recommended to restore the default firewall configura-
tion after completing a task which requires modified settings.
