I played VPN on Burst.net last week.
There something new for me. I recorded here for reference.
1) Burst.Net has budget VPS. $5.95/MONTH with Memory: 512MB GUARANTEED
It is based on OpenVZ.
2) It is only support OpenVPN, not pptpd.
3) To install OpenVPN, first enable Tun/Tap at the vePortal > Info&Security
4) When use OpenVPN client GUI on Windows 7, run it as Administrator.
5) Use Webmin to manage the OpenVPN.
Details for installation.
To share this VPN with other device, install Virtual Router to make a Wifi Hot Spot for your android, iphone, Laptop, etc.
