Configuring advanced WAN Failover settings
You can configure additional settings for WAN Failover on the Advanced tab.
Link speed
From the Link Speed drop-down list, select Automatic if you want the Edge to select the best network
speed. You can also select one of the half-duplex or full-duplex speeds that you know is compatible
with your equipment. We strongly recommend that you do not change this setting unless instructed to
by Technical Support. When you set the link speed manually, this can cause a conflict with the NIC
device during failback that does not allow WAN1 to reconnect.
Override MAC address
Some ISPs use a MAC address to identify the computers on their network. Each MAC address gets one
static IP address. If your ISP uses this method to identify your computer, then you must change the
MAC address of the Firebox X Edge external interface. Use the MAC address of the cable modem, DSL
modem, or router that connected directly to the ISP in your original configuration.
The MAC address must have these properties:
It must use 12 hexadecimal characters. Hexadecimal characters have a value between 0 and 9 or
•
between "a" and "f. "
It must operate with:
•
- One or more addresses on the external network
- The MAC address of the trusted network for the Firebox X Edge
- The MAC address of the optional network for the Firebox X Edge
You cannot set the MAC address to 000000000000 or ffffffffffff
•
To override the MAC address, select the Enable override MAC address check box, and then enter the
new MAC address in the Override MAC address field. When you are finished, click Submit.
