Getting forward secrecy enabled

[justin]

On ssllabs.com I am getting the following, even though I am using all the
recommend settings.

Here are my nginx settings:

  ssl_prefer_server_ciphers on;
  ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers "EECDH+ECDSA+AESGCM EECDH+aRSA+AESGCM EECDH+ECDSA+SHA384
EECDH+ECDSA+SHA256 EECDH+aRSA+SHA384 EECDH+aRSA+SHA256 EECDH+aRSA+RC4 EECDH
EDH+aRSA RC4 !aNULL !eNULL !LOW !3DES !MD5 !EXP !PSK !SRP !DSS";
  ssl_dhparam /etc/nginx/ssl/dhparam_4096.pem;

Any idea how I can get full forward secrecy enabled?
