Chapter 17 System Administration : Interfaces : Interface settings
  
Interface settings
In System > Network > Interface, you configure the interfaces, physical and virtual, for the FortiGate unit. There are different options for configuring interfaces when the FortiGate unit is in NAT mode or transparent mode. On FortiOS Carrier, you can also enable the Gi gatekeeper on each interface for anti-overbilling.
Interface page
Create New
Select to add a new interface, zone or, in transparent mode, port pair.
For more information on configuring zones, see Zones.
Depending on the model you can add a VLAN interface, a loopback interface, a IEEE 802.3ad aggregated interface, or a redundant interface.
When VDOMs are enabled, you can also add Inter-VDOM links.
Name
The names of the physical interfaces on your FortiGate unit. This includes any alias names that have been configured.
When you combine several interfaces into an aggregate or redundant interface, only the aggregate or redundant interface is listed, not the component interfaces.
If you have added VLAN interfaces, they also appear in the name list, below the physical or aggregated interface to which they have been added.
If you have added loopback interfaces, they also appear in the interface list, below the physical interface to which they have been added. If you have software switch interfaces configured, you will be able to view them. For more information, see “Software switch”.
If your FortiGate unit supports AMC modules, the interfaces are named amc-sw1/1, amc-dw1/2, and so on.
Type
The configuration type for the interface.
IP/Netmask
The current IP address and netmask of the interface.
In VDOM, when VDOMs are not all in NAT or transparent mode some values may not be available for display and will be displayed as “-”.
Access
The administrative access configuration for the interface.
Administrative Status
Indicates if the interface can be accessed for administrative purposes. If the administrative status is a green arrow, and administrator could connect to the interface using the configured access.
If the administrative status is a red arrow, the interface is administratively down and cannot be accessed for administrative purposes.
Link Status
The status of the interface physical connection. Link status can be either up (green arrow) or down (red arrow). If link status is up the interface is connected to the network and accepting traffic. If link status is down the interface is not connected to the network or there is a problem with the connection. You cannot change link status from the web‑based manager, and typically is indicative of an ethernet cable plugged into the interface.
Link status is only displayed for physical interfaces.
MAC
The MAC address of the interface.
Mode
Shows the addressing mode of the interface. The addressing mode can be manual, DHCP, or PPPoE.
Secondary IP
Displays the secondary IP addresses added to the interface.
MTU
The maximum number of bytes per transmission unit (MTU) for the interface.
Virtual Domain
The virtual domain to which the interface belongs. This column is visible when VDOM configuration is enabled.
VLAN ID
The configured VLAN ID for VLAN subinterfaces.
