OpenVPN Client Configuration on Windwos XP

Requirements

• A system pre-installed with Windows XP with service pack 1.
• Internet connectivity with dial-up Modem or through any
  other networking means.

Configuration Steps

1. Install The Package openvpn-gui on Windows XP.
2. Copy the file C:\program files\OpenVPN\sample-config\client.ovpn
   to C:\program files\OpenVPN\config\client.ovpn and then add or replace
   following entries in it.

   
dev tun
proto udp
remote gatekeeper.zodiacmtc.com 1194
persist-key
persist-tun
ca ca.cert
cert .cert
key .key
ns-cert-type server
tls-auth ta.key 1
comp-lzo
tun-mtu 1500


   The phrase <common name of the client system> should be replaced with
   a descriptive name of the system which is used to create the key on server.
   Preferably no space should be present in the common name of the system.
   For example one such name of the system can be "laptop-aan" which describes
   the laptop being used by AAN. In that case the key and cert file to be used
   on the client system can be named as laptop-aan.key and laptop-aan.cert
   respectively. These files along with two other files, namely ca.cert and
   ta.key should be obtained from the server. Without these files, VPN
   connections can't be established. The files other than ta.key and ca.cert
   will have to be created separately for each client system being configured
   for VPN connectivity. Starcom engineer can create and send those files
   whenever a new client system is configured for VPN based access.
   

3. Copy the ca.cert, ta.key, <common name of the system>.cert and
   <common name of the system>.key files to the configuration directory
   C:\program files\OpenVPN\config.
4. Then right click on openvpn icon on taskbar, choose and click on connect.
5. Supply the password which is provided by the person who supplied the key
   files.
6. A pop-up window show the connection status. Within few seconds, the VPN
   should be up.
7. In the browser like firefox, set the proxy server setting to the LAN IP
   of the web proxy server. (10.10.10.216 port 8080)
8. Check any external site after authenticating with the web proxy server and
   check the proxy server logs. It should show the entries for the site being
   accessed over VPN.
9. Configure e-mail clients like MS Outlook or Thunderbird to connect to the
   mail client on local network and access mails.
10. If above two steps get completed successfully, the VPN setup is complete.
