You will have to open a ticket to request a TUN/TAP device to be enabled on your VPS. If your host?s support staff doesn?t know how to do this, you may tell them to execute the following commands on the hardware node where your VPS is hosted.

vzctl stop YOUR_VEID vzctl set YOUR_VEID --devices c:10:200:rw --save vzctl set YOUR_VEID --capability net_adminn --save vzctl start YOUR_VEID vzctl exec YOUR_VEID "mkdir -p /dev/net; mknod /dev/net/tun c 10 200; chmod 600 /dev/net/tun" # iptables support vzctl stop YOUR_VEID vzctl set YOUR_VEID --iptables ipt_REJECT --iptables ipt_tos --iptables ipt_TOS --iptables ipt_LOG --iptables ip_conntrack --iptables ipt_limit --iptables ipt_multiport --iptables iptable_filter --iptables iptable_mangle --iptables ipt_TCPMSS --iptables ipt_tcpmss --iptables ipt_ttl --iptables ipt_length --iptables ipt_state --iptables iptable_nat --iptables ip_nat_ftp --save vzctl start YOUR_VEID

If it is enabled you can disregard the above quotations



Login to your VPS as root and execute the following commands

wget http://vpsnoc.com/scripts/install-openvpn.sh chmod +x install-openvpn.sh ./install-openvpn.sh

You will be prompted to enter values for your server and client certificate, feel free to accept (hit enter) the default values. Its not recommended to setup a password for your server certificate as you will have to type in the password each time you wish to start/restart the openvpn daemon.
You can however set a password for your client?s certificate since it offers extra level of protection in case your certificate and key files are compromised. You will be prompted for that password each time you connect on your VPS?s VPN.
After the script finished installing openvpn (should be very quick) the client keys and the openvpn client configuration file will be archived in /root/keys.tgz
You may use a sftp/scp client such as winscp or filezilla to download the archive on your computer.
If you already haven?t installed openvpn for windows you may do so now.
You may use winrar or 7zip to extract the content of keys.tgz in C:\Program Files\OpenVPN\config\VPN (create a folder named VPN there)
After you have extracted the files from keys.tgz in the above folder, you may start openvpn-gui from the start menu, right click the tray icon, go to VPN and click connect. After the icon turns green all your traffic will be forwarded through your VPS, no extra configuration on your browser/IM client/email client is required.
If you?re facing issues make sure that your computer clock is synchronized, if so make sure that your VPS?s clock is correct as well. If it?s not you will have to ask your host to sync it.

Download /root/keys.tgz using winscp or other sftp/scp client such as filezilla
Create a directory named vpn at C:\Program Files\OpenVPN\config\ and untar the content of keys.tgz there
Start openvpn-gui, right click the tray icon go to vpn and click connect


hopefully you can get it all sorted
