Currently we only support one IPSec VPN client, a free client from Shrew Soft
* Download and install the Shrew Soft [http://www.shrew.net/download/vpn|Windows VPN CLientClient].
* Open client and click on + (Add) to add a configuration
* Enter '''YOURNICK.yourhda.com'''. Replace YOURNICK with your actual HDA nickname, so that your DynDNS works.
