l2tp proxy ip: L2TP protocol proxy ip server build configuration

Figuring out what the heck an L2TP proxy is

Folks may have heard of the L2TP protocol, the full name of the thing is calledLayer 2 Tunneling Protocol, which is mainly used to create virtual private networks. But today we are not talking about VPN, but how to use it to build a proxy server. Simply put, it's a way to encapsulate network requests via L2TP so that the target website thinks your request is coming from another IP address.

For example, suppose you use your own broadband to access the Internet in Beijing, and connect to the server in Hong Kong through L2TP proxy, then the IP displayed on the website is the IP of the Hong Kong side. Compared with HTTP proxy, this proxy methodBetter penetration, suitable for scenarios that require a stable connection over a long period of time.

Steps to build your own L2TP proxy server

Just to be clear haha, building your own server does seem to be a bit of a gateway and requires preparation:

1. Overseas server (Hong Kong/Japan recommended)
2. Linux system (Ubuntu 20.04 is recommended)
3. At least 1GB of RAM

The installation and configuration process is a five-step process:

 Step 1: Install the necessary components
sudo apt-get install openswan xl2tpd ppp

 Step 2: Modify the ipsec configuration
echo "config setup
    virtual_private=%v4:10.0.0.0/8,%v4:192.168.0.0/16
    protostack=netkey" > /etc/ipsec.conf

 Step 3: Create the account password file
echo "username password 123456" > /etc/ppp/chap-secrets

 Step 4: Start the service
service ipsec restart && service xl2tpd restart

 Step 5: Set up NAT forwarding
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
