Managing Network Global Configurations

Use the Global Configuration Settings screen to manage existing general network settings like the default gateway and DNS servers. Set DHCP to assign the IP address or to set a static IP address, add IP address aliases, and set up services to allow external communication.

Disruptive Change

You can lose your TrueNAS connection if you change the network interface that the web interface uses!
You might need command line knowledge or physical access to the TrueNAS system to fix misconfigured network settings.

Can I configure these options elsewhere? Users can configure many of these interface, DNS, and gateway options in the Console Setup menu. Be sure to check both locations when troubleshooting network connectivity issues.

Setting Up External Communication for Services

Use the Global Configuration Outbound Network radio buttons to set up services for external communication capability.

These services use external communication:

  • ACME DNS-Authenticators
  • Anonymous usage statistics
  • Catalog(s) information exchanges
  • Cloud sync
  • KMIP
  • Mail (email service)
  • Replication
  • Rsync
  • Support
  • TrueCommand iX portal
  • Updates
  • VMWare snapshots

Select Allow All to permit all the above services to communicate externally. This is the default setting.

Select Deny All to prevent all the above services from communicating externally.

Select Allow Specific to permit external communication for the services you select. Allow Specific displays a dropdown list of the services you can select. Click on all that apply. A checkmark displays next to a selected service, and these services display in the field separated by a comma (,).

Click Save when finished.

Setting Up Netwait

Use Netwait to prevent starting all network services until the network is ready. Netwait sends a ping to each of the IP addresses you specify until one responds, and after receiving the response then services can start.

To set up Netwait, from the Network screen:

  1. Click on Settings in the Global Configuration widget to open the Global Configuration screen.

  2. Select Enable Netwait Feature. The Netwait IP List field displays.

  3. Enter your list of IP addresses to ping. Press Enter after entering each IP address.

  4. Click Save when finished.
