Installed and configured on amazon (and google) server.

The connection is established from the computer, but does not connect to the android device.
After the connection is established, no ip address is assigned to the computer.
I tried both locale bridge, and the SecureNAT.

Is this information for the server or for the client?

Could you show the VPN server log?
