Very good example to illustrate the client device traffic was redirected to the Server's gateway to Internet.

所以我也不用2.3，转回用2.2

pusey

windows版本的2.3也是可以的，我一直在用，但如果要在windows下制作证书，那就还是2.2的比较好，反正我折腾2.3，搞了很久都没有成功，但换成2.2，一下就ok了，另外，最好是在XP或是win7下搞。

上面是把OpenVPN最重要的step说出，等有时间，再把整个程序写出来，那么大家member可以跟着做。

系统连接好后，Client的PC的packets会通过HK Server的gateway走。

终于可以把OpenVPN安装在OpenWRT里了！

1. 安装openvpn package，不用安装它的GUI package

2. 做好OpenVPN选用的port number and type，我用standard，就1194 UDP port

3. 跟根据官网做certs，最重要的common name，这个是非常重要！详细看官网怎样generate certificates， keys， pems

4. On OpenWRT， using vi editor to create a file with a name "vpn.conf" which contains

1. port    1194
   
2. proto   udp
   
3. dev-type     tun
   
4. dev vpn-user
   
5. 
   
6. ca      ca.crt
   
7. cert    server.crt
   
8. key     server.key
   
9. dh      dh1024.pem
   
10. 
    
11. # enable compression
    
12. comp-lzo
    
13. 
    
14. # allow several users to connect with the same certificate
    
15. duplicate-cn
    
16. 
    
17. server  10.30.0.0 255.255.255.0
    
18. client-to-client
    
19. 
    
20. keepalive 10 120
    
21. 
    
22. push    "dhcp-option DOMAIN jl.selfip.org"
    
23. push    "dhcp-option DNS 8.8.8.8"
    
24. push    "redirect-gateway def1"
    
25. 
    
26. persist-key
    
27. persist-tun
    
28. 
    
29. user nobody
    
30. group nogroup
    
31. 
    
32. #log vpn.log
    
33. verb 3

4b. Using the following script to run openvpn with the server configuration file vpn.conf

1. openvpn --config vpn.conf

複製代碼

5. 安装Windows on PC 的Openvpn，最好选用 2.2版本。

1. remote jl.selfip.org
   
2. port 1194
   
3. proto udp
   
4. dev tun
   
5. 
   
6. comp-lzo
   
7. 
   
8. client
   
9. 
   
10. resolv-retry infinite
    
11. nobind
    
12. persist-key
    
13. persist-tun
    
14. ns-cert-type server
    
15. 
    
16. verb 3
    
17. 
    
18. ca      ca.crt
    
19. cert    client1.crt
    
20. key     client1.key
    
21. 
    
22. 
    
23. ping 10
    
24. ping-restart 60
