Oct 20, 2016 · In short, don’t use PPTP if you care at all about security when setting up a VPN. Instead, opt for a more secure protocol: OpenVPN, L2TP/IPSec, SSTP, or IKEv2. Alternatives to PPTP. Other VPN protocols are either not as easy to set up as PPTP or do not come pre-installed on popular operating systems.
Re: Microsoft PPTP VPN with Cisco IPSEC VPN OK, strange your pptp clients worked since the beginning, PPTP as you mentions uses GRE which is a portless protocol, I see on your config that you have Static PAT for PPTP and some other ports GRE does not support this so it would be normal that this does not work since the beginning. Microsoft released a security advisory on Aug 20, 2012 warning that the VPN solutions that rely on PPTP in combination with MS-CHAP v2 as the sole authentication method are vulnerable. Microsoft is aware that detailed exploit code has been published for known weaknesses in the Microsoft Challenge Handshake Authentication Protocol version 2 (MS Dec 06, 2006 · Select Microsoft in the left panel and Microsoft VPN Adapter on the right panel.

May 19, 2020 · PPTP. The Point-to-Point Tunneling Protocol (PPTP) is an older method of VPN encryption designed by Microsoft, which goes all the way back to Windows 95.
There are many VPN options and technology components available, this document will primarily focus on MS PPTP (Microsoft's implementation of Point to Point Tunneling Protocol). Other technologies will be mentioned based on two major premises: popularity and availability. Microsoft is aware that detailed exploit code has been published for known weaknesses in the Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAP v2). The MS-CHAP v2 protocol is widely used as an authentication method in Point-to-Point Tunneling Protocol (PPTP)-based VPNs. I gather the Windows VPN used to rely on PPTP, which is not considered secure. But in Windows 7/2008, it supports L2TP/IPSec, SSTP and IKEv2, and authenticates with EAP or CHAP/CHAPv2. That seems pretty up-to-date to me.

Jul 06, 2020 · PPTP is the Point-To-Point Tunneling Protocol. Invented by Microsoft in 1995, PPTP is one of the oldest and most widely supported VPN protocols still in use. It is a lightweight, fast protocol that works across nearly all operating systems. But PPTP is not without flaws. This is why I began my survey of "free" VPN clients with PPTP. However, even Microsoft acknowledges that other tunneling protocols provide much stronger security. In Windows 2000, Microsoft added support for IPsec tunneling. Today, Microsoft's Windows 2000 and XP VPN clients support both PPTP and L2TP, where L2TP tunnels are secured by IPsec. The following is a step-by-step guide of how to setup Ace VPN connection using the Point to Point Tunneling protocol (PPTP) on Microsoft Windows 7. The instructions would work on Windows Vista and Windows XP however the screen shots might look little different.
