What is l2tp Internet access: L2TP Internet access principle and configuration

What the hell is L2TP?

You may have heard of the term L2TP, but you are always confused as to what it is all about. In fact, to put it bluntly it isTunneling on the Internet的技术，好比给网络数据套了个防弹衣。跟咱们常见的代理IP搭配使用，能有效保护数据传输的隐私性——注意这里说的可不是什么代理，而是正经八百的网络安全防护。

For example, you use a proxy IP to access the site, L2TP is like adding a layer of tamper-evident packaging to the courier package. Even if someone intercepted in the middle, can not see what is inside. This combination is especially suitable for those who need toProtecting business dataorPrevent IP blockingscenarios, such as old timers who do e-commerce data collection.

How does this thing work?

The L2TP workflow is a three-step process:

1. First, with the proxy server.Shake hands and confirm your eyes.(Connection established)
2. general network datarepackageencrypted package
3. Through an exclusive channelpoint-to-point transmission

Here is an easy to confuse point: L2TP does not come with encryption, it has to be used with IPSec. It's like sending a courier with both a box and a sealing tape, double insurance is reliable.

Hands-on with L2TP proxies

Here is an example of Win10 (other systems are much the same):

1. 控制面板 → 网络和共享中心
2. 设置新的连接 → 连接到工作区
3. 选择使用我的Internet连接()
4. 输入ipipgo提供的服务器地址
5. 认证类型选L2TP/IPSec
6. 填入账号密码（找客服要）

Here's the point!pre-shared keyDon't miss this option, it's the equivalent of a secret code. Remember to look for the exact value in the ipipgo client, the key may be different for different packages.

Guidelines for handling common rollover scenes

Q: What if I can't connect to the server?
A: First check the three elements: the server address is correct, the key is not filled, the network is normal. If you are using ipipgo's dynamic residential package, remember to switch the line in the client to try.

Q: Sudden slowdown?
A: It may be that the current line is congested, it is recommended to change the node in the ipipgo client. Static residential package users can directly contact customer service to ask for an exclusive channel.

Q: How do I set up my cell phone?
A：安卓/苹果设置里都有选项，参数和电脑端基本一致。推荐直接用ipipgo的APP，傻瓜式一键连接。

Why do you recommend ipipgo?

Having used seven or eight proxy providers, ipipgo is truly unique. TheirTK Line对L2TP支持特别友好，能控制在200ms以内。最近新出的跨境专线更夸张，实测下载速度能到50Mbps+。

The price of the package is also real:

• Dynamic residential as low as $7+ for 1G of traffic
• Enterprise package with exclusive technical support
• Static IP for long term fixed services

bottom line is this.Comprehensive protocol supportLike we do crawlers often have to switch between different protocols, with his client directly check on the line, do not have to repeatedly toss the configuration.

Tips for choosing a package

Newbies are advised to start testing the waters with Dynamic Residential (Standard), which is not painful to use at $7.67/GB. If you do cross-border e-commerce this kind of business that requires a fixed IP, directly on the 35 yuan / month static package. A customer to do independent station with his static IP, account blocking rate directly down 60%.

Enterprise users remember to choose 9.47 yuan / GB package, with exclusive customer service and technical support. Last time we had a project urgently need to call the Southeast Asia IP, customer service at two o'clock in the morning to help coordinate resources, this service is no words.

Lastly, I'd like to say that the proxy services on the market are a mixed bag, and the L2TP connection of some small workshops is not stable at all. I've bought a cheap one before, and I've been disconnected for three days, and I've lost all my critical data. Since I switched to ipipgocross-border rail lineThe stability of the business has gone straight to the next level.
