Note: You cannot set MTU size if the external interface is configured using PPPoE. The PPPoE
protocol configures optimum MTU size.
To change the MTU size of the packets leaving the external interface:
1 Go to System > Network > Interface.
2 For the external interface, select Modify
3 Select Fragment outgoing packets greater than MTU.
4 Set the MTU size.
Set the maximum packet size in the range of 68 to 1500 bytes. The default MTU size
is 1500. Experiment by lowering the MTU to find an MTU size for best network
performance.
In Transparent mode, you can configure the management interface for management
access to the FortiGate unit.
1 Go to System > Network > Management.
2 Change the Management IP and Mask as required.
This must be a valid address for the network from which you will manage the
FortiGate unit.
3 Add a default gateway IP address if the FortiGate unit must connect to a default
gateway to reach the management computer.
4 Select the management Access methods for each interface.
By default in Transparent mode, you manage the FortiGate unit by connecting to the
internal or dmz interface. However, you can configure the management interface so
that you can manage the FortiGate unit by connecting to any interface.
