How to Setup your own VPN server and bypass DPI
In this tutorial I’ll teach you how to Setup your own VPN server using OpenVPN in Ubuntu 18.04.
1) You can install OpenVPN with my script if your clients live in countries with censorship like China:

You can use this script too, but it can’t bypass DPI:

2) After Installing OpenVPN on the server, your clients need to download OpenVPN client from:
3) Use scp command to transfer your client config from server to your machine. You can learn more about scp in this tutorial:

4) In order to increase your server’s TCP, copy these three lines at the bottom of /etc/sysctl.conf
net.core.default_qdisc=fq
net.ipv4.tcp_congestion_control=bbr
net.ipv4.tcp_fastopen=3
5) Then you have to install Fail2Ban.
