How to setup v2ray - a powerful technique against IP banning

It is really an useful skill for people who live in mainland China to setup a VPN(Virtual Private Network). Considering the frequently banning of VPS(Virtual Private Server) on some protocols like Shadowsocks, I prefer to use the V2Ray for at least following three advantages:

• Security: v2ray is a much more secure protocol than others.
• Convenience: there are many convenient scripts to configure v2ray
• Effectiveness: it cannot be banned when you use both v2ray and cdn. Otherwise, most other protocols could be banned according IP instead of the domain, and you need to find another one. It’s just wasting your money.

Welcome to the v2ray world! You can get a basic understanding from the following image.

• Target: setup a VPN for your own use.
• Cost: about $47 (330 RMB) per year and a bit of your rest time.
• Level: ⭐⭐⭐⭐

1. Buy a VPS

I choose the for the reason in price and convenience (support for Alipay), however, there are some other kinds of VPS server providers with appealling prices, such as

Remember to use promotion code in BandwagonHOST! It usually has a 6% discounting!

2. More Powerful techniques (for free!)

Against the banning of servers’ IP in China, we choose another powerful technique to build our VPN server, rather the directly connecting by Shadowsocks protocol.

Register your free domain

I strongly recommend you to register a free domain in freenom because of its 12-month free domain service. However, you can register a new one when the date is out for our use. By the way, it is also okay to buy a domain in any other ways.

Note: You should create an account here.

Setup CDN for the domain

After registering the domain, we need to connect it with our VPS, i.e., the CDN service. Luckily, we can use the free service provided by cloudflare.com. In its DNS dashboard, you shoud setup like following:

Note: You should gray the status button.

In the freenom dashboard -> management tools -> use custom nameservers (enter below), you need to enter you cloudflare DNS server like <name>.NS.CLOUDFLARE.COM (you can find servers in you cloudflare.com).

In the cloudflare dashboard -> SSL/TLS panel, choose the Full encryption.

Please ensure that DNS have been updated in your network by checking the response of following command:

ping <your domain>

If the response IP is same to your VPS IP, congratuation!

Install V2ray service on your VPS

We need to install v2ray service in our VPS by following command:

bash <(curl –s –L https://git.io/v2ray.sh)

and then install step by step (this script may be unavaible, please find another one in Github if it happens).

• When the script ask you to install, type 1 and then enter to install.
• When the script ask you to choose protocol, type 4 and then enter.
• When the script ask you to choose a port, type any number from 1-65535 you like, except 80 or 443. Actually, they are used specific reasons.
• When the script ask you to input you damain, do it.
• Make sure that your DNS has been updated as the last step said.
• Please just press enter to comfirm all of the remaing configuration steps.

Finish your configuration

Download v2rayN for windows platform here. Other versions is also available.

In your VPS server, input v2ray qr to get a link of generate your v2ray QR code and open it in your browser. Make sure the image of QR code is visible, then Launch v2rayN and choose Scan QR code in the screen. Your v2ray server will be added automatically.

Enjoy it!

Reference

• How to setup your shadowsocks server? When you configure your domain in freenom.com, you may get into some troubles because that the register script needs recaptcha (it may hide in the website appreance, you can see network errors in Google Chrome developer panel by press F12). Since you do NOT EVEN have access to Google, the continuing becomes impossible. Therefore, I strongly recommend you to setup you shadowsocks server in your VPS first, and then get a free domain to setup you v2ray.
