Pptp frente a l2tp ipsec
At the beginning it has many vulnerabilities but after a while it is used with IPSec.

但是当l2tp 或pptp与ipsec共同使用时，可以由ipsec提供隧道验证，不需要在第2层协议上验证隧道使用l2tp。 PPTP要求互联网络为IP网络。 L2TP只要求隧道媒介提供面向数据包的点对点的连接，L2TP可以在IP(使用UDP)，桢中继永久虚拟电路 (PVCs),X.25虚拟电路(VCs)或ATM VCs网络上使用。 VPN: SSL frente a IPSec. Las redes privadas virtuales (VPN) basadas en el estándar IPSec se están convirtiendo en una de las tecnologías llamadas a liderar el nuevo año. Están surgiendo, sin embargo, nuevas alternativas basadas en SSL que prometen una mayor sencillez a la hora de crear conexiones seguras por Internet.

NOTE: For remote PC to connect to PPTP server, it can use Windows built-in PPTP software or Third-party PPTP software.

We can also see the SAs for this connection on the Installed SAs tab. Now when you see how easy it is to setup this connection, you should consider replacing those old PPTP VPNs and replacing it with a Point-To-Point Tunneling Protocol is the oldest VPN protocol. Because the use of this protocol is almost the same as the use of the PPTP protocol, there is only an IPsec shared key that we must input on our device if we want to connect using the L2TP VPN A. Windows automatically creates an IPSec policy for L2TP connections because L2TP doesn't encrypt data. However, you might want to test a VPN L2TP connection without the security of IPSec (e.g., when troubleshooting).

PPTP should be considered extremely vulnerable, and as such, is not a viable alternative for any use that requires high security, especially when there are better options available (almost every device that supports PPTP also supports the much stronger L2TP/IPsec). PPTP should only be used for purposes where speed and location are the primary goals of VPN use (as opposed to encryption). PPTP -> El puerto 1723 en TCP. L2TP -> El puerto 1701 en TCP. IPSEC -> Además, el puerto 500 y 4500 en UDP. Estos puertos debemos abrirlos en el apartado de « Port Forwarding» de nuestro propio router. La encriptación es de 256 bit y L2TP es compatible con casi todas las plataformas, aunque sea un poco difícil ajustarlo comparado con el PPTP. Algunos problemas relativos a L2TP son la velocidad del protocolo y el hecho de que muchos ISP (internet Service Provider) puedan fácilmente bloquear las conexiones que lo utilizan. L2TP a L2TP/IPsec Layer 2 Tunnel Protocol na rozdíl od jiných VPN protokolů neposkytuje žádné soukromí nebo šifrování komunikace, která přes něj prochází. Vzhledem k tomu je typicky implementován společně se sadou protokolů známých jako IPsec pro šifrování dat před přenosem, které poskytují uživatelům soukromí a zabezpečení.

> Private free VPN-servers (L2TP/IPsec). To connect to any of the servers use: Pre-shared key, Username and Password: vpn. Updated March 17, 2021 at 9:00 am (UTC). PPTP is a network protocol that change the IP datagram into PPP packets to be transmitted over the Internet. PPTP can also be used on a private network LAN-to-LAN.
Diferencias entre los protocolos PPTP y L2TP
These protocols include Point-to-Point Tunneling (PPTP), Layer 2 Tunneling (L2TP/ Internet Protocol Security (IPsec), Secure Sockets Layer (SSL), and OpenVPN. Beyond just sounding confusing, all of these protocols present a lot of options and complexities–and most VPN providers don’t provide much explanation to why you should use any of them. As you mentioned, Layer 2 Tunneling Protocol (L2TP) and Point-to-Point Tunneling Protocol (PPTP) are two different tunneling protocols.
