1. PPTP (Point-to-Point Tunneling Protocol). Overview. Platform Compatibility. PPTP is one of the oldest VPN protocols still knocking about. L2TP (Layer Two Tunneling Protocol) is a tunneling protocol that realizes VPN (Virtual Private  The following restrictions apply to L2TP/IPsec supported on Yamaha routers.

Many modern VPNs use various forms of UDP for this same functionality. Aside from OpenVPN, some businesses use a mixture of IPSec and L2TP. Another Microsoft creation, this combination is much easier to implement off-the-shelf, and current PPTP users should find it fairly familiar. It’s not quite as secure as OpenVPN, but much safer than PPTP and it’s pretty quick as well.

L2TP/IPsecとの違いの1つは、認証するタイミングです。PPTPでは、暗号化されていない状態で認証を行います。一方、L2TP/IPsecでは、IPsecで暗号化されたトンネルの中で認証を行います。そのため、PPTPよりもL2TP/IPsecの方が、安全性が高いといわれています。 L2TP vs PPTP L2TP/IPSec y PPTP son similares en las siguientes maneras: proporcionar una lógica mecanismo de transporte para enviar PPP cargas; proporcionar túnel o la encapsulación de modo que el PPP cargas basado en un protocolo puede ser enviada a través de una red IP; dependen de la conexión PPP proceso para realizar la autenticación del usuario y la configuración de los protocolos. PPTP uses MPPE for encryption which may have some disadvantages compared to IPSEC (which is commonly used with L2TP). IPSEC can also be used on its own as a tunneling protocol and this is pretty common. An advantage with IPSEC in general would be if it's used with certificates to authenticate on the machine-level in addition to the user-level.

Both PPTP and L2TP need the PPTP & L2TP pass-through options in the firewall/router's management  To allow L2TP w/ IPSec traffic, open UDP ports 500, 1701 & 4500. Point-to-Point Tunneling Protocol (PPTP) was the first VPN protocol.
