Discovery of networked National Instruments devices (targets) by other devices (hosts) requires bi-directional communication between host and target. By default, National Instruments devices do not have communication restrictions. However, devices that are not produced by National Instruments may use firewall software as a security measure to restrict communication. National Instruments network device discovery requires access to the following ports.
|5353||UDP||Discovery of devices using the multicast Domain Name System (mDNS) protocol|
|44515||UDP||Discovery of legacy devices in safe-mode when a routable IP address is not known|
|44516||TCP||Discovery of legacy devices in safe-mode when a routable IP address is known|
|44525||UDP||Discovery of legacy devices in run-mode|
|52725||TCP||NI Network Browser utility|
|3580||UDP||web monitoring and configuration server port|
