This page shows you how to configure a [failover IP](/dedibox-ip-failover/concepts/#failover-ips) on Dedibox servers running on FreeBSD.

<Requirements />

- A Dedibox account logged into the [console](https://console.online.net)
- [Created](/dedibox/how-to/order-a-server/) a Dedibox dedicated server

## Failover IP configuration on FreeBSD

1. Connect to your server using SSH.
2. Open the network configuration file in a text editor, for example `nano`:
    ```
    nano /etc/rc.conf
    ```
3. Add the following line to the file, replace `FAILOVER_IP` with your failover IP address:
    ```
    ifconfig_em0_alias0="inet FAILOVER_IP netmask 255.255.255.255"
    ```

    Your modified configuration file should look like the following example:

    ```
    ifconfig_em0="inet IP_ADDRESS netmask 255.255.255.0"
    defaultrouter="IP_ADDRESS"
    sshd_enable="YES"
    ntpd_enable="YES"
    ntpd_sync_on_start="YES"
    syslogd_flags="-ss"
    fsck_y_enable="YES"
    ifconfig_em0_alias0="inet FAILOVER_IP netmask 255.255.255.255"
    ```
4. Save the file and exit the text editor.
5. Restart the network to activate the new IP address:
    ```
    /etc/rc.d/netif restart && /etc/rc.d/routing restart
    ```
