Is using L2TP/IPSec with a public pre-shared key secure No, it is not secure and should only be used where security is not required/important e.g. If you are streaming content that requires an IP in a different location. To understand why it is not secure read on. For wide compatibility with client devices and ease of setup the L2TP/IPSec service uses a pre-shared key for authentication. RFC 2661 - Layer Two Tunneling Protocol "L2TP" L2TP extends the PPP model by allowing the L2 and PPP endpoints to reside on different devices interconnected by a packet-switched network. With L2TP, a user has an L2 connection to an access concentrator (e.g., modem bank, ADSL DSLAM, etc.), and the concentrator then tunnels individual PPP frames to the NAS.

About Mobile VPN with L2TP User Authentication The users and groups you add to the L2TP configuration are automatically included in the L2TP-Users group. In Fireware v12.2.1 or lower, when you add a user or group to the Mobile VPN with L2TP configuration and select Firebox-DB as the authentication server, this does not automatically add the user or group for Firebox authentication. VPN protocols: IKEv2, OpenVPN, Shadowsocks - Surfshark L2TP & PPTP Outdated and not secure tunneling protocols L2TP, sometimes available as a slightly improved L2TP/IPSec, and PPTP are both old-school tunneling protocols. They are obsolete and do not offer adequate security, which is why we highly recommend to avoid both of them.
