-VLAN 1(internal LAN, interface default of FG100D, management vlan): 192.168.40.0/22  with DHCP Server and SNMP Server OmniVista 2500NMS for deploy Stellar Access Point

-VLAN 10( Office): 172.16.142.0/24

-VLAN 40( Guest): 10.0.1.0/16

I need 3 vlans can access to internet .

-Config on FG100D:

1/Create 2 sub interface on Lan interface: sub-interface vlan10 and vlan 40

2/Create Policy:

   a/Policy vlan 10 to internet: interface vlan10 to wan 1

    Have you gotten the trunking configured correctly yet on the Alcatel? Can you PING the default gateways on the Fortigate from those VLANs?

    Hi OP,

    Since you said all 3 vlans should have Internet access, I didn't see any policy allowing vlan1 to the wan interface. Either no policy allowing vlan1 to other vlans. So how could your devices in 192.168.40.0/22 initiate outbound traffic?

     

    Keep in touch. Thanks!
