System Network
This section describes how to configure your FortiGate unit to operate in your
network. Basic network settings include configuring FortiGate interfaces and DNS
settings. More advanced configuration includes adding VLAN subinterfaces and
zones to the FortiGate network configuration.
The following topics are included in this section:
• Interface
• Zone
• Network Options
• Routing table (Transparent Mode)
• Configuring the modem interface
• VLAN overview
• VLANs in NAT/Route mode
• VLANs in Transparent mode
• FortiGate IPv6 support
Interface
In NAT/Route mode, go to System > Network > Interface to configure FortiGate
interfaces. You can
• modify the configuration of a physical interface
• add and configure VLAN subinterfaces
• configure an ADSL interface
• aggregate several physical interfaces into an IEEE 802.3ad interface (models
800 and higher only)
• combine physical interfaces into a redundant interface
• add wireless interfaces (WiFi-60A and WiFi-60AM models only)
For information about VLANs, see “FortiGate units and VLANs” on page 96.
Note: Where you can enter both an IP address and a netmask in the same field, you can
use the short form of the netmask. For example, 192.168.1.100/255.255.255.0 can also be
entered as 192.168.1.100/24.
Note: Unless stated otherwise, in this section the term interface can refer to a physical
FortiGate interface or to a FortiGate VLAN subinterface.
