I've been trying to configure a Fortiwifi 40c via PPPoE for several days to replace the one you get from the company. The problem is that the firmware is 5.2.14 build764 and I control the most modern ones for my work. This one loses me a bit.
I have a username and password, as well as the operator's VLAN.
My question comes from where and how to put the VLAN to be able to connect to the internet since in the GUI there is no option in interfaces and I have created and added it by CLI in wan1, but even so it does not appear in the GUI.
Create a new VLAN interface on the Fortigate Firewall by clicking Network -> Interfaces and then clicking the + icon. Enter a name for the VLAN interface and select the physical interface to which the VLAN will be bound. Also set the VLAN ID. Configure the PPPOE interface by clicking "Network" -> "Interfaces" and then clicking the "+" icon. Select the VLAN interface you created earlier and select "PPPOE" as the connection type. Enter the required PPPOE authentication details, such as username and password. Configure the routing by clicking on "Network" -> "Routing". Add a new route by clicking on the "+" icon. Specify the destination network and the gateway. The gateway is the IP address of the router connected to the PPPOE network. Check your configuration by clicking on "Monitor" -> "IPsec Monitor". Verify that the PPPOE interface is active and that the routing tables are configured correctly. With these steps, your Fortigate router should be able to access the Internet via PPPOE and use the VLAN to transfer data between different networks.
config system interface edit <Interface-Name> set vlanid <VLAN-ID> set interface <Physisches-Interface> next end
config system interface edit <Interface-Name> set vlanid <VLAN-ID> set pppoe enable set pppoe username <Benutzername> set pppoe password <Passwort> next end
config router static edit <Eintrag-Nummer> set dst <Zielnetzwerk> set gateway <Gateway-IP-Adresse> next end
