How to setup openVPN client config for specific ip 1

If you want to use OpenVPN just for specific ips here is how :

in .ovpn file add the following :

 #don't route all traaffic
 route-nopull
 # redirect the Intranet network via the VPN
 route 172.1.0.0 255.255.0.0

Here is the breakdown:

 route-nopull

This line ensures that you do not pull route config from vpn

route 172.1.0.0 255.255.0.0

This line you tell to route all traffic for any ip starting with 172.1. to go through VPN.

if you were to set subnet to 255.255.255.0, that will route all traffic for any ip starting with 172.1.0. to go through VPN.

    "uid": "app1",
    "append": true,
    "watch": false,
    "script": "server.js",
    "sourceDir": "/home/user/app1",
    "command": "node --debug=5800"
}, {
    "uid": "app2",
    "append": true,
    "watch": false,
    "script": "bin/www",
    "sourceDir": "/home/user/app2",
    "command": "node --debug=5801"
   }

in breakdown: when you give "command", it uses that command to execute your script that you give in "script". After setting up we can execute the command
