Setting up OpenVPN

Note: Make sure the 'Start OpenVPN Client' under Services > VPN is disabled on your DD-WRT.

1. Open your browser and go to https://ironsocket.com/network
2. Select a VPN Server Address that you wish to connect to. Click the link to go to the OpenVPN site.
3. Enter your VPN Username and Password. Change the drop-down menu from 'Connect' to 'Login' and click the 'Go' button.
   
   Note: You can get your VPN credentials from the VPN Login Details section of the member's area.

4. Click 'Yourself (user-locked profile)' and download the 'client.ovpn' file to your computer.

5. Login to your DD-WRT router and navigate to Setup > Basic Setup.
6. Under Network Address Server Setting (DHCP), fill up the DNS boxes:
• Set Static DNS 1 to: 208.67.222.222
• Set Static DNS 2 to: 208.67.220.220
7. Uncheck the boxes next to the following:
• Use DNSMasq for DHCP
• Use DNSMasq for DNS
• DHCP-Authoritative
8. Set Time Settings to match your current location.
9. Click Save and Apply Settings
10. Navigate to Administration > Commands
11. Click the link below to open the Startup Script template:
• http://pastebin.com/raw.php?i=sExgzE12
12. Copy/paste the entire script to DD-WRT 'Commands' box.
13. Edit "Your_VPN_Username" and "Your_VPN_Password" (include the quotes) with your own VPN credentials.
14. Open the client.ovpn file that you've downloaded on Step 4 using Notepad (or any text editor).
15. Copy the entire content of client.ovpn and paste between ##--BEGIN--## and ##--END--## of the Startup Script on the Commands box.
    
    Note: You may delete comments (i.e. lines that start with #) to minimize the size of openvpn.conf file.
16. Find the line on the script that says 'auth-user-pass' and change to:
• auth-user-pass /tmp/ironsocket/userpass.conf
17. Click Save Startup
18. Navigate to Administration > Management and click Reboot Router
19. After your router restarts, visit our site and confirm your IP has changed in the top bar. If it has, congratulations you've now successfully setup your DD-WRT router as an OpenVPN client!

Note: To check the logs, telnet to your DD-WRT router and enter the command:

• tail -f /tmp/ironsocket.log -n 100

Troubleshooting

I am getting the message 'Authentication Failed' when trying to connect
Be sure to check that your account is still active. If it is, note that your VPN Username and Password is different than your IronSocket Website credentials. You can locate your VPN Username and Password on your VPN Login Details page.

After connecting I am unable to browse and I get disconnected after 1-2 minutes
Some routers and ISPs use abnormal UDP Network Address Translation (NAT) configurations which can result in your outgoing data jumping between different outgoing ports. This sort of connection is not supported by OpenVPN. Try switching to TCP to see if this resolves your connectivity issues. See how to do this below.

How do I switch between TCP and UDP protocols?
All of our .ovpn configuration files include both UDP and TCP connection information. By default UDP typically is used first as it appears first in the list of connection settings.

If you are using the OpenVPN Connect application you can simply adjust the settings to force the connection to use UDP or TCP. On Windows and Mac OSX this is an option in the Right-click / Control-click menu on the taskbar / menu bar icon. On iOS, in the general "Settings" area OpenVPN Connect can be selected and configured. On Android, the Preferences option can be selected by pressing the menu button within the OpenVPN Connect app.

If you are using OpenVPN Community or Tunnelblick you can edit the .ovpn file directly with a text editor and comment out the remote UDP or TCP lines. These lines appear at the bottom of the file and start with the word 'remote' and end with 'udp' or 'tcp'. To comment out a line just add a semi-colon ';' at the start of the line. For example change "remote uk-lon-1.isvpn.net 53 udp" to ";remote uk-lon-1.usvpn.net 53 udp". Save the file and re-import it into your application.
