The internal interface is a switch with either four or six physical interface connections,
depending on the FortiGate model. Normally the internal interface is configured as a
single interface shared by all physical interface connections - a switch.
The switch mode feature has two states - switch mode and interface mode. Switch mode
is the default mode with only one interface and one address for the entire internal switch.
Interface mode allows you to configure each of the internal switch physical interface
connections separately. This allows you to assign different subnets and netmasks to each
of the internal physical interface connections.
FortiGate models 100A and 200A Rev2.0 and higher have four internal interface
connections. The FortiGate-60B and FortiWifi-60B have six internal interface connections.
Consult your release notes for the most current list of supported models for this feature.
Selecting Switch Mode on the System > Network > Interface screen displays the Switch
Mode Management screen.
Caution: Before you are able to change between switch mode and interface mode all
references to 'internal' interfaces must be removed. This includes references such as
firewall policies, routing, DNS forwarding, DHCP services, VDOM interface assignments,
and routing. If they are not removed, you will not be able to switch modes, and you will see
an error message.
