Difference between l2tp and pptp: Comparison of the performance and security of the two VPN protocols

The protocol underpinnings

The old iron of the network should have heard of the L2TP and PPTP this pair of "old brothers", although they are VPN protocols, but the belly loaded with goods can be very different.L2TP this buddy is actually a stitching monster, the Microsoft PPTP and Cisco's L2F protocols kneaded together, it is like two bicycles put together into a tricycle. PPTP is much simpler, completely developed by Microsoft, as native as a home-grown watermelon.

To give a grounded example: PPTP is like an ordinary cottage, installed a chain lock can live; L2TP is equivalent to the installation of a burglar-proof door of the cell house. These two protocols in the proxy IP application is the most common to the data transmission layer shell, especially the need for long-term stable connection business scenarios.

The Fast and the Furious real test

The speed measurement thing depends on the actual scenario, we have done a comparison test with a crawler project. With ipipgo's dynamic residential IP as the carrier, PPTP transfer speed can reach 15MB/s, while L2TP is only about 8MB/s. However, it should be noted that PPTP is a double-edged sword - it runs faster because it is faster than L2TP, and it is faster because it is faster than L2TP. But be careful, PPTP this speed is a double-edged sword - running fast becauseEncryption measures are about the same as running around nakedL2TP is slower but reliable in terms of security.

Who's the best at security?

Last year there was a real case: an e-commerce platform used the PPTP protocol to do price monitoring, and as a result, the competitors were easily raked over the data. Later, it was replaced by a static residential IP of L2TP+ipipgo to plug the loophole. Here to draw the key:PPTP's MS-CHAP v2 authentication has long been brokenWhile L2TP has an IPSec encryption shield, security is a few levels higher.

However, security comes at a price, and L2TP requires the installation of certificates, which is quite dissuasive to white people. Here to teach a trick: use ipipgo client can be automatically configured, more than ten times less worry than manual operation.

// Example: Calling the ipipgo API to get L2TP configuration
curl -X GET "https://api.ipipgo.com/l2tp_config" -H "Authorization: Bearer your_api_key"

Practical Selection Guide

The choice of protocol depends on the specific business requirements:

• PPTP for ad-hoc testing: lightning-fast configuration for short and quick projects
• L2TP for long-term business: security first, recommended with static residential IPs
• Cross-country data transfer: directly on ipipgo's TK line, the speed is as steady as an old dog!

There is a misconception to correct: not all scenarios require the strongest encryption. For example, for public data collection, it is more cost-effective to use PPTP. But when it comes to account login business, I beg you to choose L2TP.

Frequently Asked Questions QA

Q: Does using L2TP slow down the internet speed?
A: The measured impact is about 15%-20%, but ipipgo's cross-border dedicated line can make up for this loss, and sometimes it is faster than the bare connection instead.

Q: How do I choose a package for my enterprise business?
A: Dynamic residential (enterprise) package comes with protocol optimization, supports simultaneous configuration of a variety of VPN protocols, management background can see the real-time traffic

Q: What if I need to manage thousands of IPs at the same time?
A: Directly find customer service to 1v1 customized program, their API support batch operation, than manual configuration to save a hundred times!

A matching program compiled from our three years of hands-on experience:

• Individual users: dynamic residential (standard) with PPTP, $7.67/GB cabbage price
• Studio: Dynamic Residential (Enterprise) + L2TP, $9.47/GB with team management features
• Enterprise: static residential packages, $35/IP fixed export, business stability pulling full

The last nagging sentence: the protocol is well chosen, the seal less trouble. When it comes to the need for high anonymity of the business, it is recommended to directly on the ipipgo SERP API service, specializing in anti-climbing strict website, pro-test effective.
