Look at the listening socket to see the result of the setup.

  $ netstat -na | grep :631.*LISTEN
  tcp        0      0 127.0.0.1:631           0.0.0.0:*               LISTEN
  tcp6       0      0 ::1:631                 :::*                    LISTEN

In this example from my machine it is listening on 127.0.0.1 which
isn't available to remote systems.  Compare this to ssh port 22 which
is open for all addresses.

  $ netstat -na | grep :22.*LISTEN
  tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN
  tcp6       0      0 :::22                   :::*                    LISTEN
