Most probably your version of Apache (v2.2?) does not support elliptic
curves (ECDHE); therefor you won't get forward secrecy with IE (except for
IE11 on Windows 8 which supports DHE).
You may either have a look at the Debian projects version of Apache
(because they backported EC-Support to Apache 2.2) or (probably better) put
an nginx in front of Apache because only the very latest versions of Apache
support Diffie Hellman parameters stronger than 1024bit.
