Disable the network discovery port

You can disable the network discovery port on the Pearl device using the Admin panel so that services can no longer discover the Pearl device systems using multicast DNS (mDNS). The network discovery port on the Pearl device is port 5557 and is enabled by default.

Important considerations

  • You cannot connect to the Admin panel using a DNS-based service discovery if you disable the network discovery port, see Connect using a DNS-based service discovery.
  • The network discovery port must be enabled to use the NDI feature on Pearl-2.

Disable the network discovery port using the Admin panel

  1. Log in to the Admin panel as admin, see Connect to the Admin panel.
  1. From the Configuration menu, select Network and then the Interfaces tab. The Network Interfaces page opens.
  2. Uncheck Make this device discoverable on the network as <uniqueID.local>, then click Apply.
