In recent time, spent a lot of time in the configuration of OpenVPN. Spend a lot of time to solve the resource sharing access, the client through the server to ask the amount of external network.

After a hard work finally succeeded. Now write down the approximate process as a note

1 Windows version OpenVPN installation. Download the corresponding system version directly installed. In addition, to install OpenSSL, it is recommended to download the WINOPENSSL installation directly.

Note: The server side should be checked all. Otherwise, the certificate cannot be created.


2 Creating a Certificate

2.1 Server, open the installation directory under Easy-rsa, first modify the Vars-bat-sample, modify the content.

Note that common name, others like it.

2.2 Run the command line (note Administrator permissions)

Init-config

VARs

Clean-all

2.3 Create CA:BUILD-CA, get ca,crt,ca.key two letter public documents. Where CA.CRT is a public file, both servers and clients are used.

2.4 Create a service-side certificate: Build-key-server Server certificate file name, get 3 files: SERVER.CRT,SERVER.KEY,SERVER.CSR.

2.5 Create a client certificate: Build-key Client (the certificate file name for clients), get 3 files: CLIENT.CRT,CLIENT.KEY,CLIENT.CSR.

Note: Different client certificates are generated, noting that common fields are distinguished.

2.6 Create Dee-Herman Exchange Password: BUILD-DH, this is optional. The build time is about more than 10 minutes. Get 1 Files: Dh4096.pem (different version file names may be different)

2.7 Open Tls-auth, optional, non-essential

Open one by one Genkey one by one secret Keys/ta.key

Get 1 Files: Ta.key.

2.8 If you need to create a new user again, the command line executes VARs, and then directly Build-key (the new user file name).

3 Configuration Run

3.1 Server-side:

Copy under openvpn/easy-rsa/keys/: CA.CRT, Server.crt,server.key,dh4096.pem,ta.key

In the Openvpn/sample-config directory, copy the Server.ovpn to the Openvpn/config directory, and then open it with a text editor. The content is modified as follows:

port:1194

Proto UDP

Dev Tun #注: tested, in the window system, want to access the Internet through the server, Tap/tun can be. No problem. It's not a myth to tap.

CA ca.crt

Cert SERVER.CRT

Key Server.key

DH Dh4096.pem

Server 10.8.0.0 255.255.255.0

Push "Route 0.0.0.0 0.0.0.0" #推网关. In the window system, you want to surf through the server, preferably with

Ifconfig-pool-persit ipp.txt #此处注意: Server-side runtime to pay attention to permissions, non-administrator rights may not be able to write to the default installation directory C disk, the runtime prompts an error.

Push "Redirect-gateway def1 bypass-dhcp"

Push "Dhcp-options DNS ..." #推DNS. in the window system, you want to surf through the server, preferably with

Push "Dhcp-options DNS ..." # in Window system, want to surf through the server, preferably plus

Verb 3

4 Key: Clients to access the server-side network resources, be sure to enable Internet Connection Sharing on the server-side physical network card ...

On the server-side physical network card properties, open Internet Connection Sharing: Allows other network users to connect through the computer's Internet connection.

This allows access to server-side shared resources ... If not, push the gateway ....

If you want to use the server-side extranet, it is best to push the DNS together .... These three things to do, the server intranet must pass. Most of the external network is available.

If it is not, server-side if it is the server system, directly installed NAT service.
