92 Firebox X Edge e-Series
3 Below the Advanced tab, select the Enable override MAC address check box.
4 In the Override MAC address text box, type the new MAC address for the Firebox X Edge external
network.
You must enter the MAC address as a hexadecimal number.
Do not use extra characters, such as spaces or hyphens.
5 Click Submit.
You must restart the Firebox to see the changes.
Note
If the Override MAC address field is cleared and the Firebox X Edge is restarted, the Firebox X Edge
uses the default MAC address for the external network.
To decrease problems with MAC addresses, the Firebox X Edge makes sure that the MAC address you
assign to the external interface is unique on your network. If the Edge finds a device using the same
MAC address, the Firebox changes back to the standard MAC address for the external interface and
restarts again.
