@HaniAbuelkhair6735 you cannot natively change the DHCP lease time from the GUI. You have to use FlexConfig

@HaniAbuelkhair6735 no, the configuration is applied via the GUI.

The screenshots above are literally all that is required to change the DHCP lease time:

Create a FlexConfigObject - specify the command dhcp lease <value> just change the value of 86400 to the value you require.
Create a FlexconfigPolicy and include the object you created above, then deploy the policy.

I'm doing above solution at Cisco Firepower 1010 Threat Defense (FTD) using Firepower Device Manager (FDM) but I'm having this error:

Any ideas?

@Piotr Kotłowski this works for me on FDM 7.3, you may need to upgrade in order for that command to be supported.
