MTU

To improve network performance, you can change the maximum transmission unit
(MTU) of the packets that the FortiGate unit transmits from any interface. Ideally, this
MTU should be the same as the smallest MTU of all the networks between the
FortiGate unit and the destination of the packets. If the packets that the FortiGate unit
sends are larger, they are broken up or fragmented, which slows down transmission.
Experiment by lowering the MTU to find an MTU size for best network performance.

To change the MTU, select Override default MTU value (1500) and enter the
maximum packet size. For manual and DHCP addressing mode the MTU size can be
from 576 to 1500 bytes. For PPPoE addressing mode the MTU size can be from 576
to 1492 bytes.

Log

Select Log to record logs for any traffic to or from the interface. To record logs you
must also enable traffic log for a logging location and set the logging severity level to
Notification or lower. Go to

Log & Report > Log Config

to configure logging locations

and types. For information about logging see

“Log & Report” on page 353

.

Configuring interfaces

Use the following procedures to configure FortiGate interfaces and VLAN
subinterfaces.

•

To bring down an interface that is administratively up

•

To add interfaces to a zone

•

To add an interface to a virtual domain

•

To change the static IP address of an interface

•

To configure an interface for DHCP

•

To configure an interface for PPPoE

•

To add a secondary IP address

•

To add a ping server to an interface

•

To control administrative access to an interface

•

To change the MTU size of the packets leaving an interface

•

To configure traffic logging for connections to an interface

To add a VLAN subinterface

See

“To add a VLAN subinterface in NAT/Route mode” on page 65

.

SSH

To allow SSH connections to the CLI through this interface.

SNMP

To allow a remote SNMP manager to request SNMP information by connecting to

this interface. See

“Configuring SNMP” on page 99

.

TELNET

To allow Telnet connections to the CLI through this interface. Telnet connections

are not secure and can be intercepted by a third party.

Note:

In Transparent mode, if you change the MTU of an interface, you must change the MTU

of all interfaces to match the new MTU.
