, a simple, safer, faster and more modern VPN protocol.

 

Usage

First, get the script and make it executable :

 

curl -O https://raw.githubusercontent.com/Angristan/openvpn-install/master/openvpn-install.sh
chmod +x openvpn-install.sh

 

Then run it :

 

./openvpn-install.sh

 

You need to run the script as root and have the TUN module enabled.

 

The first time you run it, you'll have to follow the assistant and answer a few questions to setup your VPN server.

 

When OpenVPN is installed, you can run the script again, and you will get the choice to :

 

• Add a client
  
• Remove a client
  
• Uninstall OpenVPN
  

In your home directory, you will have .ovpn files. These are the client configuration files. Download them from your server and connect using your favorite OpenVPN client.

 

Features

• Installs and configures a ready-to-use OpenVPN server
  
• Iptables rules and forwarding managed in a seamless way
  
• If needed, the script can cleanly remove OpenVPN, including configuration and iptables rules
  
• Customisable encryption settings, enhanced default settings (see

Running two servers with different configuration

 

I hardcoded like this

 

1. After a clean install with UDP mode
   
2. clone server.conf into server2.conf (manual edit UDP => TCP mode)
   
3. in server2.conf, change ip 10.8.0.1 to 10.9.0.1
   
4. add 10.9.0.1 in IPtables
   
5. at line 838 or close to it, add
   sed -i 's|server2.conf' /lib/systemd/system/openvpn/server2.service
   
6. service openvpn@server restart and service openvpn@server2 restart
   
7. try lsof -i:1194 your port number, you will see both UDP & TCP openvpn services are running
