This tutorial is going to show you how to change the IP address on the FreeNAS Server. If you have a working DHCP server on your network during FreeNAS installation, the FreeNAS Server will be able to get the IP address from the DHCP server. But, in case you don’t have a DHCP server, you will need to specify the IP address manually. This tutorial will show you how to do this.
First, boot FreeNAS and you should see this screen after boot.
Type 1 and press enter to get into the network interface configuration. You will see all the network interfaces listed. In my case I only have one network interface.
Type 1 and press Enter. Then answer the following question.
Q: Reset Network Configuration? (Y/N)
A: Press N
Q: Configure Interface for DHCP? (Y/N)
A: Press N
Q: Configure IPv4? (Y/N)
A: Press Y
And then give a new name for the interface or simply press Enter. Next type the IP address you want to assign to the server.
IPv4 Address: 192.168.2.200 (its just an example. You can change this to anything you want)
IPv4 Netmask: 255.255.255.0
Q: Configure IPv6? (Y/N)
A: Press N (I do not need to configure IPv6 at the moment).
Now FreeNAS will reset the network interface. Now you should see your new IP address displayed.
