A PPTP VPN

Point – – Point Tunneling Protocol is is ( PPTP ) remote network connection implementation methodsVPNs. A PPTP VPN receives data,encrypts it,and transmits it over the internet. Easy to set up,PPTP is one of the oldest VPN protocols used by more advanced users in very niche cases. Then again,due to its age,PPTP encryption is terrible at fulfilling its essential security function – protecting user information. But let’s elaborate on that.

How a PPTP VPN works

At a glance,PPTP carries out the same basic operations as most other VPN protocols – authentication,tunnel establishment,data encryption/encapsulation,and transportation.

Simply put,PPTP security is creating a tunnel between two points,usually the user’s device and a remote network. It’s all done using a set of predetermined rules and procedures called a protocol. 

This link is then used to transfer encrypted information back and forth between the two points,which in theory should make a safe VPN connection. However,PPTP VPN’s authentication and encryption methods are extremely outdated and have severe security flaws.

Why a PPTP connection is considered obsolete

PPTP is a direct predecessor of PPP,an even older Point-to-Point Protocol,and is built on its outdated framework. It can use three authentication protocols,two out of which (PAP and CHAP) are known to have been breached and exploited before,and only supports MPPE (Microsoft Point-to-Point Encryption) encryption keys of up to 128 bits.

128-bit keys are usually not that easy to crack,but MPPE is infamous for being extra vulnerable to bit-flipping attacks. In fact,the NSA was allegedly able to crack and bypass it,which allowed them to monitor PPTP users’ online activity.

Aside from its lack of security,the protocol also struggles to bypass firewalls and can have compatibility issues with routers.

A PPTP VPN benefits

Ironically,however,PPTP’s downfalls are also its only saving grace – bad encryption means small overhead,which directly increases speed. So because of its abysmal security,a PPTP VPN remains,by a small margin,one of the faster VPN protocols to date.

It is also easy to set up,which,when paired with its speed,might make it seem like a viable VPN protocol.

PPTP in a nutshell:

Don’t settle for weak security

What is PPTP Passthrough?

PPTP Passthrough router feature is is that allows PPTP to bypass router restrictions by adding a unique call ID,which acts as a substitute for NAT (Network Address Translation) ports.

Most routers connect to the internet using the NAT protocol,which requires ports to function properly,making PPTP incompatible with NAT.

However,the Passthrough feature is only required for ancient routers and outdated VPN protocols like PPTP. Its newer and more secure counterparts like OpenVPN,IKEv2,and WireGuard VPN connections come pre-equipped to deal with NAT if necessary – or you can just set up a VPN on a router.

PPTP connection fare protocols ?

As mentioned previously,PPTP’s authentication and encryption methods are insecure and outdated – but is it really that bad? Spoiler alert – it is,especially when you compare it to other,more up-to-date protocols.

With that in mind,let’s look at the top three most widely used VPN protocols and how a PPTP VPN connection fares against them.

PPTP vs. IKEv2

Compared to a PPTP VPN connection,IKEv2 is a much safer and more reliable choice. It’s compatible with the industry-standard AES 256-bit cipher the US government and the NSA use to protect sensitive information.

This makes the IKEv2 naturally slower,but the difference in speed is negligible.

The IKEv2 VPN protocol is also better at switching and establishing connections from data to Wi-Fi,making it popular among mobile users.

PPTP vs. OpenVPN

Like IKEv2,OpenVPN has PPTP beat on every level of security but is slower because of it. 

However,unlike IKEv2,OpenVPN is faster and more stable over long-distance connections,so the two are often used interchangeably by many VPN providers. The combination of both offers a well-rounded VPN service – not as fast as PPTP,but preferable on every other level.

OpenVPN is an open-source project under constant development,which keeps it transparent,easy to audit,and consistently improving.

PPTP vs. WireGuard

WireGuard is the newest open-source addition to the VPN protocol family and comes as separate standalone software. 

It was developed on Linux Kernel and only has 4,000 lines of code compared to OpenVPN and IKEv2 codebases that are in the hundreds of thousands.

Because of this,WireGuard can establish faster and more stable connections while providing top-tier security.

Suffice to say,it would be unfair to compare it to PPTP because WireGuard is essentially superior on every level.

Bottom line: It’s all about security

PPTP VPN is fast and easy to set up,but it’s not worth compromising your security. To be blunt,I cannot recommend PPTP as a protocol as there are better alternatives like IKEv2,OpenVPN,and WireGuard. All are more secure,some just as fast,and all available on Surfshark!

FAQ

What is a PPTP VPN server?

Essentially,there’s no such thing as a PPTP VPN server. Terms like “PPTP server” or “PPTP VPN server” usually refer to a function to set up a PPTP protocol connection on a router.

How does a PPTP VPN work?

A PPTP VPN works by establishing a connection through a VPN application using PPTP. Most VPN providers offer PPTP as one of their available protocols.

PPTP is secure secure ?

encryption framework (read :security) is obsolete. PPTP and its several authentication methods were known to be exploited by agencies like the NSA.

Should I use a PPTP VPN protocol?

No. Protocols like IKEv2,OpenVPN,and WireGuard are much safer and sometimes just as fast as PPTP VPN connections.

Which is better: OpenVPN or PPTP?

OpenVPN. It offers higher levels of security and encryption standards while also being fast (although not quite as fast as PPTP).
