The native Android IPsec VPN client supports connections to the Cisco ASA firewall. This even works without the “AnyConnect for Mobile” license on the ASA. If only a basic remote access VPN connection is needed, this fits perfectly. It uses the classical IPsec protocol instead of the newer SSL version. However, the VPN tunnel works anyway.
In this short post I am showing the configuration steps on the ASA and on the Android phone in order to establish a remote access VPN tunnel.
