Point-to-Point Tunneling Protocol (PPTP) is one of the earliest VPN protocols designed to create secure connections between remote devices and private networks. While once widely used for its speed and simplicity, PPTP is now considered outdated due to weaker encryption standards compared to modern VPN protocols.
Point-to-Point Tunneling Protocol (PPTP) is a VPN protocol developed by Microsoft in the 1990s to enable secure data transfer between users and private networks. It uses a control channel over TCP and encapsulates data using GRE tunnels. Known for its fast speeds and easy setup, PPTP became a common choice for early VPNs before newer, more secure protocols like IKEv2, OpenVPN, and WireGuard replaced it.
PPTP works by creating a virtual tunnel between your device and the VPN servers, allowing your data to travel securely across the internet. Here’s how the process unfolds:
Your VPN client initiates a connection with the VPN server using TCP port 1723, establishing a control channel for communication.
PPTP sets up a GRE (Generic Routing Encapsulation) tunnel that wraps your data packets for transmission across public networks.
The server verifies your credentials using MS-CHAPv2 authentication before allowing access to the VPN.
Once authenticated, your data travels through the encrypted tunnel to the VPN server, where it’s decrypted and sent to its destination.
Responses from websites or apps are encrypted by the server and sent back through the same tunnel to your device.
In short, PPTP offers a quick and straightforward way to create VPN connections, but its outdated encryption methods make it less secure than modern protocols.

PPTP used to be popular for a reason. It’s simple, fast, and works almost anywhere. Here’s what made it stand out:
PPTP is easy to set up because it’s already integrated into most operating systems and routers. Users can create a connection within minutes without downloading extra software or performing complicated configurations.
Being one of the oldest VPN protocols, PPTP continues to work across older and newer devices alike. It supports Windows, macOS, Linux, Android, iOS, and many routers, making it a practical choice for maintaining access on aging hardware.
PPTP provides faster performance than many legacy VPN protocols thanks to its lightweight encryption. It’s ideal for low-risk activities such as streaming, basic web browsing, or bypassing simple regional restrictions without slowing down your internet connection.
Once authenticated, your data travels through the encrypted tunnel to the VPN server, where it’s decrypted and sent to its destination.
PPTP’s minimal processing demands make it suitable for devices with limited power or slower internet speeds. Even on outdated systems or weak networks, it runs smoothly without consuming significant CPU or bandwidth resources.
While PPTP remains easy to use, it no longer meets today’s security or reliability standards. Here’s where it falls short:
PPTP relies on RC4-based 128-bit encryption, which can be cracked using today’s computing power, making it unsafe for anyone who values online privacy, sensitive data protection, or secure communications.
The MS-CHAPv2 authentication process used by the PPTP protocol has serious security loopholes. Attackers can exploit these weaknesses to intercept login credentials and decrypt traffic within minutes, exposing user data.
Because PPTP uses GRE for tunneling instead of common VPN ports, it’s easily identified and blocked by most firewalls. For users in workplaces, schools, or regions with internet censorship, PPTP isn’t the most reliable option.
Once authenticated, your data travels through the encrypted tunnel to the VPN server, where it’s decrypted and sent to its destination.
The PPTP protocol doesn’t use Perfect Forward Secrecy, meaning if one encryption key is compromised, past and future sessions can also be decrypted. Modern protocols avoid this risk through more advanced key exchange systems.
PPTP passthrough is a router feature that allows PPTP VPN connections to move through firewalls and NAT (Network Address Translation) systems that would otherwise block them. It helps routers handle the specific type of traffic used by PPTP, ensuring a stable and complete connection between the device and the VPN server.
PPTP relies on GRE for tunneling, which many NAT-based routers cannot process correctly. Enabling passthrough lets the router recognize and forward these GRE packets, allowing the VPN session to connect and remain active.
As PPTP has declined due to major security flaws, PPTP passthrough has also become less relevant. Modern VPN protocols like OpenVPN and WireGuard manage NAT traversal securely on their own, without needing a separate passthrough function.
PPTP laid the foundation for modern VPN technology, but it’s now overshadowed by faster, more secure, and more reliable alternatives. Here’s how it stacks up against the protocols that replaced it:
L2TP (Layer 2 Tunneling Protocol) builds upon PPTP by combining it with L2F to provide users with stronger encryption and better stability. While PPTP is faster due to weaker encryption, L2TP when paired with IPSec provides far greater security and is the safer choice for protecting sensitive data.
SSTP (Secure Socket Tunneling Protocol) is Microsoft’s successor to PPTP, designed to fix its major security flaws. It uses SSL/TLS encryption over port 443, allowing it to bypass firewalls easily. Compared to PPTP, SSTP offers far stronger security, better reliability, and native support in Windows, though it’s less flexible on non-Windows platforms.
OpenVPN outperforms PPTP in nearly every aspect. It uses robust AES encryption, supports multiple ports and protocols, and can bypass firewalls easily. PPTP is quicker to set up, but OpenVPN offers unmatched reliability, cross-platform compatibility, and protection against modern cyber threats.
IKEv2 is faster, more secure, and more stable than PPTP, particularly on mobile networks. It automatically reconnects after switching between Wi-Fi and cellular data, making it ideal for smartphones and tablets. PPTP can’t match IKEv2’s encryption strength or resilience against network interruptions.
WireGuard represents the new standard in VPN performance and simplicity. It’s lightweight, uses state-of-the-art cryptography, and delivers both speed and security. Compared to PPTP, Wireguard is more efficient, harder to block, and vastly more secure, making PPTP obsolete by modern VPN standards.
PPTP was originally used to create secure remote connections between users and private networks, especially for business VPNs and remote access. Today, it’s mostly used for testing, legacy systems, or basic connections that don’t require strong encryption.
Yes. PPTP is considered obsolete because its encryption and authentication methods can be easily compromised. Most modern VPNs and operating systems have replaced PPTP with safer, faster, and more stable protocols like OpenVPN and WireGuard.
PPTP uses weak 128-bit RC4 encryption (susceptible to bit-flipping attacks) and relies on MS-CHAPv2 authentication, both of which have known vulnerabilities. It’s also easily blocked by firewalls and doesn’t support Perfect Forward Secrecy, leaving older sessions at risk if a key is compromised.
L2TP when paired with IPSec offers far stronger encryption and better reliability than PPTP. While PPTP may connect faster, L2TP/IPsec is the safer and more practical choice for users who care about privacy and data protection.
PPTP is rarely used today, except in older routers, outdated operating systems, or legacy enterprise setups that haven’t been upgraded. Most modern VPNs have phased it out entirely in favor of more secure and efficient tunneling protocols.
A PPTP VPN server is a network endpoint configured to accept connections using the PPTP protocol. It handles user authentication, builds the GRE tunnel, and routes traffic between the VPN client and the internet or private network.
PPTP can deliver fast speeds because of its low encryption overhead, but it’s not secure or reliable for gaming. Modern protocols like WireGuard or IKEv2 provide better stability, lower ping, and better protection against DDoS attacks.
No. PPTP is no longer recommended for secure browsing, streaming, or gaming. Its encryption is outdated, and can be easily exploited. Choosing modern protocols ensures faster, safer, and more private VPN connections.
PureVPN no longer offers PPTP as an option, but it can still be set up manually on certain devices and routers. The protocol is available only for compatibility purposes, and users are strongly advised to use OpenVPN, IKEv2, or WireGuard instead.
