System DHCP

You can configure DHCP server or DHCP relay agent functionality on any FortiGate
interface or VLAN subinterface.

A FortiGate interface can act as either a DHCP server or as a DHCP relay agent. An
interface cannot provide both functions at the same time.

This section describes:

•

Service

•

Server

•

Exclude range

•

IP/MAC binding

•

Dynamic IP

Service

Go to

System > DHCP > Service

to configure the DHCP service provided by each

FortiGate interface. You can configure each interface to be a DHCP relay or a DHCP
server or you can turn off DHCP services.

Figure 20: DHCP service list

Note:

To configure DHCP server or DHCP relay functionality on an interface, the FortiGate unit

must be in NAT/Route mode and the interface must have a static IP address.

Interface

List of FortiGate interfaces.

Service

The DHCP service provided by the interface (none, DHCP Relay, or DHCP

Server).
Edit/View icon. Select to view or modify the DHCP service configuration for

an interface.
