• Android L2TP/IPSec VPN mini-howto — BrainBlog – I would have preferred that my Android 1.6 device supported OpenVPN out of the box. Unfortunately, this is only available for rooted devices and a bit of suffering. Instead, I went for configuring IPsec inside L2TP VPN server. All of it stuffed into an old and low-end Soekris net4511 board running Voyage Linux.
• How to set up a VPN server for Android Clients | Android Apps by Doenter Limited – Have problems with connecting your Android device to a VPN server? In this how-to, we intend to cover server configuration that are known to work with Android clients.

  You probably also need to configure firewalls and routing in order for the server to work as you intend. That is not covered here.

  This page is far from complete, and when time permits new configurations will be added.
