Connecting to an Endian UTM Appliance Via IPsec XAUTH Using Android

Version 3.0

Applies to platform: Any device running Android.
Updated on: 13 May 2014

This lesson describes how to connect a smartphone or tablet device with Android to an existent and running IPsec XAUTH installation on the Endian UTM Appliance 3.0 using PSK (password) authentication.


Remember that PSK and certificate-based connections are mutually exclusive, so you can't have both in one single connection. This lesson introduces only the PSK method, which is simpler and the most widely used.


The Endian UTM Appliance should run version 3.0 (or higher) of the software, since XAUTH is a feature introduced in that version.

The connection via IPsec XAUTH requires the following data, that should have been previously configured on the VPN/IPsec server:

  1. The IP address or hostname of the IPsec XAUTH server (i.e., of the Endian UTM appliances where the IPsec server runs).
  2. The PSK secret, i.e., the password of the IPSsec tunnel, that can be retrieved under Menubar > VPN > IPsec, by clicking on the Edit icon next to the connection, and then looking in the Authentication box.
  3. The username and password of the XAUTH user; which can be retrieved from Menubar > VPN > Authentication > Users, and the user must be allowed to use IPsec XAUTH.

You should write the above mentioned data down or remember it, since you will have to enter them in the corresponding configuration sections of your Android device.
