Chapter 1 What’s New for FortiOS 5.2.1 : Usability Enhancements : DHCP-related Improvements in the Web-based Manager
  
DHCP-related Improvements in the Web-based Manager
A number of improvements have been made in the web-based manager, relating to DHCP:
A DHCP Server column has been added to the interface list that shows which interfaces have been enabled as a DHCP server and the assigned IP range.
The DHCP Client List has been improved by adding device icons and changing the Expires column to show the amount of time left on the DHCP lease.
New addressing modes have been added to support IPv6 and PPPOE. The option for IPv6 will only appear if it has been enabled in the web-based manager, while PPPOE options only appear if IPv4 addressing is set to PPPOE as well.
Options have been added to DHCP Monitor, allowing DCCP leases to be revoked and IP reservations to be added or edited.
Advanced DHCP configuration can now be done through the web-based manager. To enable this feature, the following syntax must be used in the CLI:
config system global
set gui-dhcp-advanced enable
end
After this has been enabled, an Advanced menu can be expanded when configuring DCHP on a network interface.
