DHCP client optimization

In 7.2.2, FortiExtender has optimized its DHCP client module by introducing the renew DHCP lease command in its CLI, and checking and renewing DHCP lease information on its GUI. The following two new options have also been introduced under interface configuration:

• defaultgw — Enable/Disable using the gateway IP acquired from DHCP server. This option is enabled by default.

• dns-server-override — Enable/disable using the DNS servers acquired from DHCP server. This option is enabled by default.

  ### execute interface dhcpclient-renew [interface name]
  “manually renew dhcp lease on certain interface”
  e.g. renew WAN port DHCP lease
  # execute interface dhcpclient-renew wan
     renewing dhcp lease on wan

  ### config system interface
  “defaultgw and dns-server-override are shown when the interface mode is dhcp”
  edit <name>
  set mode dhcp
  ……
      set defaultgw enable
      set dns-server-override enable
