IP/MAC binding & reserving a DHCP IP address for FortiGate firewall

IP/MAC binding & reserving a DHCP IP address for FortiGate firewall:

2.    Reserving a DHCP IP address for a particular MAC address (IP/MAC binding)

Use the CLI command config system dhcp reserved-address to reserve an IP address for a particular client identified by its device MAC address and type of connection. The DHCP server then always assigns the reserved IP address to the client. 

Syntax:

config system dhcp reserved-address

edit <name_str> - the number in the IP/MAC binding table

set ip <address_ipv4> - IP address value

set mac <address_hex>  - MAC address value

set type {regular | ipsec}

end

Note: An IP address bound to a MAC address must be in the range of IP addresses (start-IP to end-IP) from an existing DHCP server already configured on the FortiGate. 

Delete DHCP IP MAC Binding:

If we want to delete IP and MAC binding then execute the following command.

Syntax:

config system dhcp reserved-address

delete <name_str>

end
