> The interface assignment rules can be changed here and might be necessary to set the preferred interface for managing Unraid - *use with care, usually there is no need to change*.
>
> **eth0** is the main interface used to manage the Unraid system. The other interfaces are optional and may be used as desired.
> Every interface must be uniquely identified by its MAC (hardware) address.
>
> The interface assignment is stored on the flash device under */config/network-rules.cfg*. This file can be viewed with any editor, but it is recommended to make changes via the webGUI only.<br>
> Deleting the file *network-rules.cfg* from the flash device will restore automatic interface assignment after a system reboot.
