Hi, Usually VLAN1 is reserved for internal use. It depends of the hardware you have but if it's not working for VLAN1, most likely VLAN 1 is used by FortiOS.

      Hi Anthony,

       

      we performed this solution for vlan100 or vlan200 but it doesn't work for vlan1.

       

      Thank you.
