Initial Configuration

For more details check out the FreeNAS Quick Start Guide.

Connecting to FreeNAS

To connect to FreeNAS point your browser to the FreeNAS server’s URL. If you forgot it will be shown on the console of the server:

FreeNAS Console 1

When you connect to the web interface you will see a window like this:

FreeNAS Alert


In the top right corner the alert icon is flashing. Click on it to see what the problem is.

You will see a box describing the alert like this:

FreeNAS Alert - No Password

In this case it is telling us to set a password for the admin user. It is also a good idea to change the username from the default of admin to something else so it is hard for people to guess your username and password.

Change the Admin Username

To change the admin username go to Account -> Admin Account -> Change Admin User.

FreeNAS Change Admin User 1

Enter your new username (you can also put your real name in if you like but it is not necessary) and click the Change Admin User button.

FreeNAS Change Admin User 2

Change the Admin Password

To change the password of the admin account go to Account -> Admin Account -> Change Password.

FreeNAS Change Password 1

Enter your password and confirm it. You should leave the checkmark in for the root account’s password too. Click the Change Admin Password button.

FreeNAS Change Password 2

Network Configuration

Even though you can get to the web interface FreeNAS will probably need a few more settings to be set before the network is fully ready. There are also a few thing in the network settings to make FreeNAS more secure.


FreeNAS can handle multiple network interfaces. You could have separate network cards for your internal network and the internet for example. Or you could have a dedicated network card for iSCSI. Most home setups will only have a single interface though. To configure an interface go to Network -> Interfaces -> View Interfaces.

FreeNAS View Interfaces

You will see a list of the currently configured network cards on your server. If the one you want to configure is in the list, click on it and then click on the Edit button at the bottom of the window. If your interface isn’t listed click on the Add Interface button.

FreeNAS New or Existing Interfaces

Pick the interface from the NIC drop down box.

Give your interface something descriptive in the Interface Name box.

If your server will get its IP address automatically from your router or another server check the DHCP box.

If your server has a static IP address enter that in the IPv4 Address box and select the correct subnet mask from the IPv4 Netmask drop down box.

FreeNAS Interface Settings

Scroll down and click the OK button.

Global Configuration

There are a few settings that affect the whole FreeNAS server instead of a single interface to set them go to Network -> Global Configuration.

FreeNAS Global Configuration 1

If you want to give your FreeNAS a name other than freenas change it in the Hostname box.

If you have your own domain you can enter the fully qualified domain name  in the Domain box. Otherwise you can leave it as local or lan.

In the IPv4 Default Gateway enter the IP address of the router you use to connect to the internet. It is usually or for most home networks.

For the three Nameserver boxes you can enter the DNS servers you want to use for the FreeNAS server. If any of your existing interfaces use DHCP the DNS servers from those interfaces will already be active.

If your computer is connected to the same router as the FreeNAS server you can find the settings for DNS servers and the default gateway but going to a command prompt and using the command ipconfig /all on a Windows computer or the ifconfig command on a Mac, Linux, or BSD computer.

FreeNAS Global Configuration 2

You can ignore the other boxes for now and click the Save button.
