Create VPN in GCP

Given that we have a GCP account, now let’s start creating VPN in GCP.

Create Project

Create VM in Compute Engine

Because VPN doesn’t require too much hardware, the machine should just use the very basic one. So as to make it cheaper.

Create ShadowSocksR Server

# run this command
curl -O https://raw.githubusercontent.com/teddysun/shadowsocks_install/master/shadowsocks-all.sh | sudo bash

Then you should have parameters for configuring the shadow socks R.
Eventually you will get:

Congratulations, ShadowsocksR server install completed!
Your Server IP        :  xx.xxx.xxx.xx 
Your Server Port      :  12180 
Your Password         :  PASSWORD 
Your Protocol         :  auth_chain_a 
Your obfs             :  plain 
Your Encryption Method:  aes-256-cfb 

Your QR Code: (For ShadowsocksR Windows, Android clients only)
 ssr://MzUuMjI5LjMxLjE0OjEyMTgwOmF1dGhfY2hhaWabcTphZXMtMjU2LWNmYjpwbGFpbjpVblZuWVd4emMzSXJNWE0vP29iZnNwYXJhbT0= 
Your QR Code has been saved as a PNG file path:

Create firewall rule

To allow traffic to shadow socks server, we should open the firewall for the server port.
Here, you should have the port comes from shadow socks configuration to TCP protocol.

Test

Then import the server configuration by copying the ssr URL, you should be able to use that now!
