OpenVPN Quick start

https://openvpn.net/index.php/open-

source/documentation/howto.html

Download and install OpenVPN installer (64bits)

https://openvpn.net/index.php/download/community-

downloads.html

Steps for building up VPN

1. Install OpenVPN

2. Initialize the environment

3. Edit the var for information

4. Create rootCA

5. Create the server private/public key pair

6. Create the client public/private key pair

7. Build Diffie Hellman paramaters

8. Check generating key

9. Copy the client configure file

10. Run open VPN server

11. Copy the client configure file

12. Run open VPN client

Step1 : Install OpenVPN

Download and install OpenVPN installer (64bits)

https://openvpn.net/index.php/download/community-

downloads.html

OpenVPN GUI

Step2 : Initialize the environment

Check Easy-rsa context in your install path

My Install path : D:\Program Files\OpenVPN\easy-rsa

Step2 : Initialize the environment

Easy-rsa path : D:\Program Files\OpenVPN\easy-rsa

Run batch file “init-config.bat”

Step3 : Edit the var.bat for information

Edit your easy-rsa folder

path

Edit the KEY_COUNTRY,

KEY_PROVINCE, KEY_CITY,

KEY_ORG, KEY_EMAIL and

the other parameters,

according to your needs.

Don't leave any of these

parameters blank.

Step4 : Create rootCA

Run “var.bat”, the file

that we just edited

Run “clean-all.bat”

Run “build-ca.bat” to

create the rootCA

– Organizational Unit

Name : user

– Common Name : RTU

– The other setting :

default

Step4 : Create rootCA

Check import items in

running “build-ca.bat”

to create the rootCA

1. Organizational Unit

Name : user

2. Common Name : RTU

3. The other setting :

default

Step5 : Create the server private/public key pair

Install OpenVPN

I

Run “build-key-

server.bat keyName”

Example :

“build-key-server.bat

server”

Check item

1. Organizational Unit

Name : user

2. Common Name : RTU

3. The other setting :

default

4. Password : 12345678

5. Certificate

Step5 : Create the server private/public key pair

Check item

1. Organizational Unit

Name : user

2. Common Name : RTU

3. The other setting :

default

4. Password : 12345678

5. Certificate

Step 6 : Create the client public/private key pair

Run “build-key.bat

keyName”

Example :

“build-key.bat client1”

Check item

1. Organizational Unit

Name : user

2. Common Name :

client1

3. The other setting :

default

4. Password : 12345678

5. Certificate

Step 6 : Create the client public/private key pair

Check item

1. Organizational Unit

Name : user

2. Common Name :

client1

3. The other setting :

default

4. Password : 12345678

5. Certificate

Step 7 : Build Diffie Hellman parameters

Run “build-dh.bat ””

This program will generate 1024bit RSA key

Step 8 : Check generating key

Key path : D:\Program Files\OpenVPN\easy-rsa\keys

Check client’s crt and server’s crt aren’t empty.

Step 9 : Copy the Server configure file

Open Server configuration

Copy file from key folder into config folder

1. ca.key,

2. ca.crt,

3. server.key,

4. server.crt,

5. dh1024.pem

Copy server configure file from sample

rename server_3600.ovpn

Key folder - D:\Program Files\OpenVPN\easy-rsa\keys

Config folder - D:\Program Files\OpenVPN\config

Step 9 : Copy the Server configure file

Modify setting in server configure

1. TCP connection : proto tcp

2. Dh file : dh dh1024.pem (default : dh2048.pem)

3. VPN domain : 192.168.77.0 255.255.255.0
