You need to be carefull with the ordering inside the ssh config file. 
To quote the man ssh_config:
      Since the first obtained value for each parameter is used, more 
host-spe-
      cific declarations should be given near the beginning of the file, 
and
      general defaults at the end.
That is: Put the 'Host *' section at the end.
