Fortigate Firewall Dialup VPN configuration

#Remote access vpn L2TP over IPsec
This example uses a locally defined user for authentication, a Windows PC or Android tablet as the client, and net‑device is set to enable in the phase1‑interface settings. If net-device is set to disable, only one device can establish an L2TP over IPsec tunnel behind the same NAT device.
