Description
Select the types of administrative access permitted on this interface.
Allow secure HTTPS connections to the web-based manager through
this interface.
Interface responds to pings. Use this setting to verify your installation
and for testing.
Allow HTTP connections to the web-based manager through this
interface. HTTP connections are not secure and can be intercepted by a
third party.
Allow SSH connections to the CLI through this interface.
Allow a remote SNMP manager to request SNMP information by
connecting to this interface. See “Configuring SNMP” on page 143.
Allow Telnet connections to the CLI through this interface. Telnet
connections are not secure and can be intercepted by a third party.
To change the MTU, select Override default MTU value (1 500) and
enter the MTU size based on the addressing mode of the interface
• 68 to 1 500 bytes for static mode
• 576 to 1 500 bytes for DHCP mode
• 576 to 1 492 bytes for PPPoE mode
• up to 16 110 bytes for jumbo frames (FortiGate models numbered
3000 and higher)
This field is available only on physical interfaces. VLANs inherit the
parent interface MTU size by default.
For more information on MTU and jumbo frames, see “Interface MTU
packet size” on page 95.
Select the blue arrow to expand or hide this section and add additional
IP addresses to this interface. See “Secondary IP Addresses” on
page 96.
Optionally, enter a description up to 63 characters long.
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.
Configuring an ADSL interface
The information that you need to provide for the ADSL interface depends on the
addressing mode your ISP requires you to use. Static addressing using IPOA or
EOA requires only an IP address and netmask. If you are using dynamic
addressing, you need to configure it as described in “Configuring DHCP on an
interface” on page 88 or “Configuring an interface for PPPoE or PPPoA” on
page 90.
To configure an ADSL interface, your FortiGate unit cannot be in Transparent
mode.
Go to System > Network > Interface. Select Create New or select the Edit icon
of an existing interface. In the Addressing mode section, select IPoA or EoA.
