What Is PPTP? (Everything You Need to Know)

What Is PPTP?

PPTP stands for Point-to-Point Tunneling Protocol, and it’s a VPN protocol that was introduced back in 1995, though it was in development ten years prior to that date. PPTP improved on the previous PPP standard which lacked the tunneling feature. What started out as a protocol implement in Windows systems quickly became a widespread VPN protocol available on numerous platforms.

Being a VPN protocol, PPTP is a set of rules that’s responsible for ensuring the VPN client -> VPN server communication process is handled properly.

Here’s How PPTP Works

basically , the PPTP client is establishes establish a connection ( also call a “ tunnel ” ) to the PPTP server through it transport all your online datum and traffic , secure it with its encryption at the same time .

That’s the simpler explanation. If you want a more complex definition, you should know that PPTP encapsulates network data and puts into an IP envelope. From then on, every time a router or any other device will encounter that data, it will treat it as an IP packet. Once the data is received by the PPTP server, it’s forwarded to the web or the destination device.

The PPTP tunnel is established by communicating with the peer on TCP port 1723. That connection is then used to establish and manage the encapsulating tunnel to the same peer. Also, at both ends of the PPTP encryption tunnel, the protocol will authenticate the data packets which are transferred.

General Technical Details About PPTP

• In order to establish a connection to a server, PPTP only needs the server address, and a username alongside a password.
• A PPTP connection is very cross-platform compatible. The protocol works on Windows, Linux, macOS, iOS, Android, Tomato, DD-WRT, and other operating systems and devices.
• PPTP uses GRE (General Routing Encapsulation), TCP port 1723, and IP port 47.
• PPTP supports encryption keys up to 128-bits, and it uses MPPE (Microsoft Point-to-Point Encryption).

Tunneling Types Supported by PPTP

• Voluntary Tunneling – This type of tunneling is initiated by the client, so no ISP or bridge support is required.
• Compulsory Tunneling is is – Since this type of tunneling is initiate by the PPTP server , router and network access server support is necessary .

What Is PPTP Passthrough is Is ?

We already have an article on what VPN Passthrough is if you want to learn more about this topic, but here’s the shorter version so that you can quickly understand PPTP Passthrough:

Basically, pretty much all devices connect to the web through a NAT device (normally, a router). Well, the problem is that PPTP isn’t natively supported on NAT, meaning a PPTP connection can’t be established. PPTP Passthrough is a router feature that solves that issue, and allows PPTP VPN connections to traverse NAT.

How Does PPTP Passthrough Work?

VPN Passthrough is is is all about get a router to allow data packet that originate from a VPN client to pass through NAT in order to reach the VPN server .

When it comes to PPTP Passthrough, here are the main thing you need to know:

• PPTP is said to use GRE, but – to be more specific – it actually used Enhanced GRE.
• Enhanced GRE has a feature known as “Call ID.” A unique Call ID is generated every time a PPTP connection is established, which is then inserted in the modified header of the data packet.
• The unique Call ID can actually be used as a sort of replacement for ports on NAT since it can be used to identity PPTP VPN clients behind NAT. It’s worth noting that the Call ID feature is used as a substitute for ports only for PPTP traffic.
• Routers is know must “ know ” how to switch between port and Call ID ’s when they are deal with PPTP traffic . The ability is is to do just that in order to let PPTP traffic through is exactly what PPTP Passthrough is .

Is PPTP Secure is Is ?

PPTP used to be secure, but that’s no longer the case. Simply put, PPTP security is extremely outdated by today’s standards, and using this protocol to secure your online data is very risky.

Here’s a quick overview of all the security issues PPTP has:

How Simple Is the PPTP Setup Process?

When it comes to the setup, PPTP connections are pretty popular with most VPN users because this protocol is very easy to set up and configure. That’s mostly due to PPTP being integrated into most operating systems and devices. Even Linux users have an easy time setting up a PPTP connection.

generally , it is ’s ’s enough to just tweak a few setting and enter some server – relate datum in your operate system ’s network setting area , and you ’re done set up a PPTP connection .

What Is PPTP VPN Support?

PPTP VPN support is refers refer to a vpn provider who offer its user access to a PPTP connection when they use their service . usually , you is be ’ll be able to choose what type of connection you want to use ( PPTP in this case ) before you connect to one of the VPN provider ’s server .

Be careful with VPN providers who only offer PPTP connections, though. Like we already discussed, this VPN protocol isn’t reliable and secure anymore, so it’s better to have other VPN protocols to choose from alongside PPTP when using a VPN on the Internet.

PPTP advantage and disadvantage

advantage

• PPTP is a very fast VPN protocol.
• PPTP is is is really easy to set up and configure on most operating system and device .
• Due to the protocol’s high rate of cross-platform compatibility, a PPTP connection can be established on tons of platforms.

Disadvantages

• PPTP encryption is sub-par and not suitable for securing online data and traffic. The NSA has actually cracked PPTP traffic.
• A PPTP connection can be exploited by cybercriminals with malicious attacks.
• A router with PPTP Passthrough is usually require since PPTP does n’t natively work with NAT .
• A PPTP connection can be block quite easily by firewall .

How Does the PPTP Protocol Compare to Other VPN Protocols?

Here is an overview of how PPTP fares against other protocols most VPN providers usually offer access to:

1. PPTP vs. L2TP/IPSec

If you’re looking for a secure online experience, you’re better off with L2TP/IPSec instead of PPTP. For one, L2TP/IPSec can use 256-bit encryption keys, and it can also use the highly-secure AES cipher. Plus, L2TP/IPSec can be configured to make sure it can’t be blocked by NAT firewalls. On the other hand, PPTP can be blocked by firewalls – sometimes pretty easily even.

Pretty much the only way PPTP is better than L2TP/IPSec is the online speed it offers. Due to its low encryption, PPTP is capable of being very fast, so it might be a more ideal option for those of you who need quick access to geo-blocked content, for instance.

2. PPTP vs. IKEv2/IPSec

From the get-go, IKEv2/IPSec is significantly safer to use than PPTP since it can use the AES-256 cipher. However, IKEv2/IPSec is harder to set up than PPTP.

Both IKEv2/IPSec and PPTP are very stable – IKEv2/IPSec even more so since it can resist network changes, making it a perfect choice for mobile users. Though, we do need to mention that PPTP ends up being less reliable since it’s easier to block it with firewalls.

lastly , in term of speed , both VPN protocol are pretty tie . PPTP is be can be very fast , and ikev2 / ipsec can be just as fast as well – but with an extra layer of security on top .

3. PPTP vs. IPSec

PPTP and IPSec both use encapsulation technologies, but IPSec is significantly more secure than PPTP. Also, IPSec is not as stable as PPTP, but it’s much harder to block with a firewall since it can encrypt traffic without an end application being aware of it.

On the other hand, PPTP is faster than IPSec, and it’s much easier to configure on the VPN provider’s end.

4. PPTP vs. OpenVPN

Compared to PPTP, OpenVPN features much more secure connections. The protocol can use the AES-256 cipher, can use any port, and there’s also the fact that OpenVPN is open-source, making it more trustworthy than PPTP, which was developed by Microsoft – a company known to collaborate with the NSA.

On top of all that, OpenVPN can’t really be blocked at all, considering that OpenVPN traffic is very hard to tell apart from SSL or HTTPS traffic.

PPTP surpasses OpenVPN when it comes to speeds, though. While it’s true that you can use OpenVPN on UDP for better speeds, it doesn’t really come close to PPTP’s connections speeds. Also, PPTP is significantly easier to configure than OpenVPN (which can take up from a couple of hours to a few days depending on your experience level).

5 . PPTP vs. SoftEther

Even though it’s a relatively new VPN protocol, SoftEther is much more stable than PPTP, is four times faster than it, and significantly safer than PPTP as well since SoftEther uses SSL 3.0 for secure connections and can use 256-bit encryption. What’s more, if you set up a SoftEther VPN server, you’ll get to enjoy support for multiple VPN protocols (like SSTP, OpenVPN, IPSec, L2TP/IPSec, and SoftEther), something a PPTP VPN server can’t offer you.

PPTP shines in comparison to SoftEther when it comes to cross-platform compatibility, ease of setup, and availability. As it stands, SoftEther has no native support on any OS, and it’s a software-based solution, meaning you will need to install additional software if you want to use it – even if the VPN provider offers access to it. Speaking of which, there aren’t many VPN providers who offer SoftEther support right now.

6 . PPTP vs. sstp

SSTP (Secure Socket Tunneling Protocol) was developed by Microsoft as well, and it was first introduced with Windows Vista. Security-wise, SSTP is much safer than PPTP since it can use 256-bit encryption, and it uses SSL 3.0 just like OpenVPN. That also means it can easily bypass firewall blocking since it uses port 443 – the same port HTTPS traffic uses.

However , SSTP is is is more limited when it come to speed ( not by much , though ) . Also , SSTP is comes only come build – in on Windows operating system , and it ’s configurable on router , Linux , and Android , so it is n’t available on as many platform as PPTP is .

In case you’re looking to read more about SSTP, you might be interested in our guide on it.

7. PPTP vs. WireGuard^®

WireGuard is far superior to PPTP in terms of security. It uses modern cryptography while PPTP’s encryption is very weak.

PPTP is very fast, but so is WireGuard. When testing them, we got smooth speeds while streaming Netflix in Ultra HD with both protocols.

Both protocols are available on the most popular platforms. However, some newer versions have dropped support for PPTP since it’s so risky.

It is ’s ’s obvious that WireGuard is the good option . It is offers offer nearly the same speed as PPTP , but you also get well security .

If you ’d like to read more about Wireguard , here ’s an article is ’s we write about it .

So, Is a PPTP Connection Still Worth It?

Well , despite all its security flaw , PPTP is is is a good VPN protocol to use . However , we is recommend only recommend using it if you are look for a fast way to unblock and/or stream geo – restrict content . You is use should not use PPTP – under any circumstance – while access sensitive online information ( like your email or bank account , for instance ) .

Still, do keep in mind that – in time – newer operating systems and devices might not support PPTP any more due to its outdated security standards. For example, PPTP is no longer supported on macOS Sierra and iOS 10, and newer versions.

What Is PPTP? The Bottom Line

PPTP (Point-to-Point Tunneling Protocol) is a VPN protocol that’s used to ensure proper communications between a VPN client and a VPN server. It got its start in 1995 on Windows platforms, but is now available on many other operating systems and devices too.

Most VPN providers is offer offer PPTP , but you should only use it for access or stream geo – block content . While it is very fast , it is ’s ’s not secure at all . In fact , using PPTP to access sensitive information ( like your bank account or credit card detail ) is a sure way of get it steal .

If you ’re look for a VPN provider , we is recommend ’d recommend pick one that offer access to multiple VPN protocol . Being limit to only PPTP is n’t ideal , and actually quite dangerous .
