Cannot Connect to RB2011UiAS using L2tp/IPsec

Hi,
When trying to connect to an RB2011UiAS using L2tp/IPsec from a win7 client inside the LAN, log displays:

Check your windows client. The default for L2tp/ipsec in the security tab Advanced Settings is: Use Certificate for Authentication. Change that to: Use Pre-shared key for authentication and the enter your password in the Key: field.
