Configuring system settings : Configuring network settings : Configuring the network interfaces
Configuring the network interfaces
The System > Network > Interface tab displays the FortiMail unit’s network interfaces.
You must configure at least one network interface for the FortiMail unit to connect to your network. Depending on your network topology and other considerations, you can connect the FortiMail unit to your network using two or more of the network interfaces. You can configure each network interface separately. You can also configure advanced interface options, including VLAN subinterfaces, redundant interfaces, and loopback interfaces. For more information, see “About FortiMail logical interfaces”, and “Editing network interfaces”.
 
If your FortiMail unit is not properly deployed and configured for the topology of your network, including network interface connections, email may bypass the FortiMail unit.
To access this part of the web UI, your administrator account’s:
• Domain must be System
• access profile must have Read-Write permission to the Others category
For details, see “About administrator account permissions and domains”.
To view the list of network interfaces, go to System > Network > Interface.
 
GUI item
Description
Name
Displays the name of the network interface, such as port1.
If the FortiMail unit is operating in transparent mode, this column also indicates that the management IP address is that of port1. For more information, see “About the management IP”.
Type
Displays the interface type: physical, VLAN, redundant, or loopback. For details, see “About FortiMail logical interfaces”.
Bridge Member
In transparent mode, this column indicates if the port is on the same bridge as the management IP. By default, all ports are on the bridge. See “Editing network interfaces” for information on bridged networks in transparent mode.
IP/Netmask
Displays the IP address and netmask of the network interface.
If the FortiMail unit is in transparent mode, IP/Netmask may alternatively display bridging. This means that “Do not associate with management IP” has been disabled, and the network interface is acting as a Layer 2 bridge. If high availability (HA) is also enabled, IP and Netmask may alternatively display bridged (isolated) while the effective HA operating mode is slave and therefore the network interface is currently disconnected from the network, or bridging (waiting for recovery) while the effective HA operating mode is failed and the network interface is currently disconnected from the network but a failover may soon occur, beginning connectivity. For more information, see “Effective Operating Mode” and “Virtual IP address”.
IPv6/Netmask
Displays the IPv6 address and netmask of the network interface. For more information about IPv6 support, see “About IPv6 Support”.
Access
Displays the administrative access and webmail access services that are enabled on the network interface, such as HTTPS for the web UI.
Status
Indicates the up (available) or down (unavailable) administrative status for the network interface.
• Green up arrow: The network interface is up and can receive traffic.
• Red down arrow: The network interface is down and cannot or receive traffic.
To change the administrative status (that is, bring up or down a network interface), see “Editing network interfaces”.
