A very basic VPN protocol based on PPP. The PPTP specification does not actually describe encryption or authentication features and relies on the PPP protocol being tunneled to implement security functionality.

Mar 15, 2016 · Because L2TP VPN data is double encrypted and authenticated, it will usually be slower than the same data transmitted via PPTP or OpenVPN. Acceptable Uses. L2TP/IPsec is a highly flexible VPN protocol and can be used for most VPN applications. It is natively supported on most devices and should be your default option if OpenVPN isn’t an option. PPTP vs. L2TP/IPSec. As you might have guessed, L2TP/IPSec is better than PPTP. Some of the features that make L2TP/IPSec superior include: • The ability to be used with 256 bit encryption keys • It can use the AES cipher • It can be configured so that NAT firewalls cannot block it. PPTP can easily be blocked by firewalls. L2TP/IPsec is just as easy and quick to set up as PPTP, but is much more secure at the cost of slightly reduced speed. Yet, because the L2TP protocol uses UDP port 500, there are chances that the VPN connection will be detected and blocked by some firewalls. L2TP security and speed . Why L2TP/IPsec is popular:

Sep 11, 2019 · In 1998, security analyst Bruce Schneier published an important paper on PPTP, and it made grisly reading for users. Or at least it should have. Or at least it should have. According to Schneier, the protocol’s weakest point was its Challenge/Response Authentication Protocol (CHAP), closely followed by its RC4-based MPPE encryption. PPTP is a tunneling protocol just like L2TP is - it does not provide security. 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. Mar 02, 2017 · Serious security vulnerabilities have been found in this protocol. L2TP VPN. L2TP VPN uses the Layer 2 Tunneling Protocol to implement a VPN. In this protocol, the entire L2TP packet, including the L2TP header and payload, is sent within a UDP. Once an L2TP tunnel is established, higher-level protocols run through the tunnel. PPTP is the only VPN protocol supported by some devices (for example, the Asus RT-AC66U WiFi router). If PPTP is configured to only use the most secure options, does its use present any security vulnerabilities? The most secure configuration of PPTP is to exclusively use: MPPE-128 encryption (which uses RC4 encryption with a 128bit key)
