l2tp protocol ip purchase: L2TP protocol ip purchase configuration process

What is the L2TP protocol? Let's figure it out before we start.

A lot of white first heard of the L2TP protocol is confused, in fact, this thing is a network transmission "courier". The biggest difference with the ordinary proxy IP is that it will be outside your packet set of two layers of protective shell (professionally called double encapsulation), equivalent to the courier on the anti-drop foam + reinforced cardboard box. This feature makes it especially suitable for scenarios that require stable transmission, such as overseas e-commerce batch shelves of goods, or multinational logistics system docking.

Attention! When using the L2TP protocol with a proxy IP, theMust ensure that both devices support the protocol. Just like when you want to send an international courier, you have to make sure that the post office in the receiving country can handle this type of packaging. Here to praise the service of ipipgo, their static residential IP packages are open by default to support the L2TP protocol, without having to toss the application to open.

Hands down the right L2TP dedicated IPs to buy

When choosing a package on the ipipgo website, don't just look at the price. Focus on the "Protocol Support" column in the product parameters and recognize the L2TP logo. Recommended choicesStatic Residential IPThe addresses in such IP pools are home broadband resources and are not easily blocked by the target sites.

Don't close the page after you've placed your order.Focus on saving three things: Server Address, Pre-Shared Key (PSK), Account Password. These three are like the key to your front door, the password to your fingerprint lock, and the access card; you can't get in without one of them.

A guide to avoiding pitfalls in real-world configurations

Take Windows as an example, follow the steps below don't skip steps:

1. Control Panel - Network and Sharing Center
2. Set up a new connection - Connect to Workspace
3. Select "Use my Internet connection ()". 4.
4. Enter the server address (e.g. us-static01.ipipgo.net). 5.
5. Select "Use L2TP/IPsec with Pre-Shared Key" for Security Type.
6. Fill in the PSK key (found on the order details page).

Common error handling:
- Error 789: Check if PSK is copied with too many spaces
- Error 691: Confirm that the account password is case-sensitive
- No Internet connection: check "Send all traffic through" in properties

Advanced maneuvers only for veteran drivers

Brothers who need to manage IPs in bulk can call ipipgo's API interface to switch nodes automatically. It's only about ten lines of code to write a rotation script in Python:

import requests
api_url = "https://api.ipipgo.com/v1/switch"
params = {
    'key': 'Your API key',
    'protocol': 'l2tp',
    'region': 'us'
}
response = requests.get(api_url, params=params)
print(response.json()['new_server'])

Remember to set theMTU value adjusted to 1400Around, it can effectively solve the problem of incomplete loading of some websites. This parameter is equivalent to adjusting the maximum size of express parcels to avoid getting stuck in transit.

QA First Aid Kit

Q: What is the difference between L2TP and regular proxies?
A: Just like the difference between an ordinary highway and a freeway, L2TP has a dedicated channel + double encryption, suitable for transferring important data

Q: What should I do if my IP is blocked?
A: In ipipgo background point "emergency IP" button, 3 seconds to generate a new address. It is recommended that customers who buy static packages enable the automatic IP change function.

Q: Will using multiple IPs at the same time conflict?
A: Add multiple connections in the NIC settings and distinguish them with different port numbers. It is recommended to have a separate connection for each service

As a final rant, there are three things to look for when choosing a proxy service provider for the L2TP protocol:Whether it supports protocol native access, whether there is a fixed port configuration, whether it can provide backup servers. Service providers like ipipgo with TK leased line will automatically switch routes in case of network fluctuations, which is much more worry-free than building your own server.
