To configure a DHCP server for an interface
After configuring an interface to be a DHCP server (using the procedure
“To configure
an interface to be a DHCP server” on page 81
), you must configure a DHCP server for
the interface.
1
Go to
System > DHCP > Server
.
2
Select Create New.
3
Add a name for the DHCP server.
4
Select the interface
5
Configure the DHCP server.
The IP range must match the subnet address of the network from which the DHCP
request was received. Usually this would be the subnet connected to the interface for
which you are added the DHCP server.
6
Select OK to save the DHCP server configuration.
To configure multiple DHCP servers for an interface
If an interface is connected to a network that includes routers connected to different
subnets, you can:
1
Configure computers on the subnets to get their IP configuration using DHCP.
The IP range of each DHCP server must match the subnet addresses.
2
Configure the routers for DHCP relay.
3
Add multiple DHCP servers to the interface, one for each subnet.
When a computer on one of the connected subnets sends a DHCP request it is
relayed to the FortiGate interface by the router, using DHCP relay. The FortiGate unit
selects the DHCP server configuration with an IP range that matches the subnet
address from which the DHCP request was received and uses this DHCP server to
assign an IP configuration to the computer that made the DHCP request. The DHCP
configuration packets are sent back to the router and the router relays them to the
DHCP client.
Exclude range
Add up to 16 exclude ranges of IP addresses that FortiGate DHCP servers cannot
assign to DHCP clients. Exclude ranges apply to all FortiGate DHCP servers.

#
The ID number of each exclude range. ID numbers are assigned
sequentially by the web-based manager. When you add or edit exclude
ranges from the CLI you must specify the ID number.
