Hi Koumbia

Download the Fortigate configuration, open it using notepad or notepad++ and search by port1.

See where port1 is used. You might need to fix/change some of the firewall configuration.

Thank you for your feedback, i don't understand why when i use 'set mode dhcp' and 'next' i have this error

Hello Koumbia,

As per your config and the error message, it seems like you are trying to set the port 1 as DHCP client whereas port 1 is configured to serve a DHCP pool within DHCP configuration. You either have to change the interface within DHCP setting or use another port as DHCP client.

Thanks,

Hi Kumbia,
Follow Atul's advice and probably you will find the issue. Just to add to his comment, the DHCP server settings can be found under 'conf system dhcp server'.
