DHCP request failed after inserting Fortigate (Transparent Mode)

Hi Guys,

As per subject above, does dhcp broadcast is blocked by fortigate?.

Based on Fortigate KB, transparent mode will not change or interrupt existing network configuration.

Static IP is required in order  for client behind Fortigate to access internet, appreciate if someone can clarify or guide recommended setting for Transparent mode. Thanks

Testing Configuration/ Enviroment:

ADLS Modem (DHCP Enable) -> Fortigate (Transparent Mode) -> Notebook
