Hi , 

    We have a Fortigate 90E , when i try to create a new VLAN configuration in any one of the physical interface , i'm not able to get internet while directly connecting the port and laptop with a working ethernet cable. Anyone has faced this issue ?

If you configure a Vlan on a physical interface and then connect a PC to that interface, you need to configure vlan tag too on PC, otherwise it will not works.

    Hi, you can look at this, but probably you would need the network drivers installed from the manufacturer of the nic.

    L.E. Are you trying to create a interface on the FortiGate with a vlan id/tag ? If so, please make sure that the port in the switch is configured in trunk and that vlan is allowed on the port where you are connecting the FortiGate.
