PPTP Protocol Explained: In-depth analysis of the PPTP protocol

What exactly is the PPTP protocol?

Proxy IP old iron should have heard of the word PPTP, but what exactly is going on may be a bit confused. Simply put, PPTP is like a courier packer, our packets of data in a special way packaging transmission. This protocol was born in 1999, the most important feature is thatSimple configuration, windows comes with support, a few mouse clicks and it works.

However, it's important to note that PPTP is slowly starting to be phased out on many platforms now. For example, Apple devices have not been supported since iOS 10, mainly because of its older encryption. But why do people still use it now? It's because it's inintranet penetrationrespond in singingdevice compatibilityIt does have advantages in terms of security, and is especially suitable for use in smart home devices or corporate intranets, which do not require high security.

Fantastic combination of Proxy IP and PPTP!

Here's the point! We do proxy IP service ipipgo, found that many users use PPTP protocol to manage distributed servers. To give a real case: a cross-border e-commerce inventory synchronization customers, they use PPTP to distribute servers in more than 20 countries to form a private network, and then through ipipgo's static residential IP to do the data relay, successfully solved the problem of cross-region data delays.

Here's a practical configuration template for you (take a small notebook and write it down):

 Server Side Settings
pptpd localip 192.168.0.1
pptpd remoteip 192.168.0.2-100

 Client-side connection commands
pon configfile test.pptp

But be warned folks, there are three things to keep in mind when messing with proxies with PPTP:

1. Try to use it with a static IP (like ipipgo's $35/month package)
2. Avoid transmitting sensitive data
3. Change connection passwords regularly

Don't step in the pits when comparing protocols

Let's pull out the common protocols and walk them around:

As you can see from the table, PPTP is best suited for organizations that need toFast IP switchingThe scenarios. For example, when using ipipgo's dynamic residential IP to do crawling business, the speed of switching IP with PPTP protocol is more than 3 times faster than other protocols.

Guidelines for the clearance of operational problems

The QA session goes a long way:

Q: Why does my PPTP keep dropping out?
A: Ninety percent of the MTU value is not adjusted well, try to change the value to 1400, or not change ipipgo's TK line, stable batch of

Q: What can I do if my phone can't connect to PPTP?
A：Android machine in the APN settings to add a "dun" parameter, apple users ... suggest directly change to use ipipgo APP client!

Q: How do I choose a package for enterprise applications?
A: average daily traffic <50GB choose dynamic enterprise version, the need for fixed exit IP closed eyes into the static residential packages

IPIPGO's one-of-a-kind tips

The secret of our dynamic residential package is the self-developed IP pool rotation algorithm. For example, when user A visits an e-commerce site, the system will automatically assign IPs that have successfully visited the site, and this intelligent matching function saves more than 30% of traffic than traditional proxies.

Focus on the three features that business users love the most:

• Unused traffic can be rolled over to the next month
• Supports simultaneous binding of 5 terminal devices
• Automatic bandwidth expansion from 2-5am 50%

Finally, a piece of advice: PPTP is good, but do not take it as a master key. Need a long and stable connection to the scene, or recommended on the ipipgo cross-border line, after all, professional things to professional agent services to do.
