I suppose you want to ssh to your localmachine when you are nowhere.
For that, you can ssh to your externalserver.com, and then ssh to your
localmachine.local.

On the local machine : 

  localmachine$ ssh -R5022:localhost:22 externalserver.com

You can automaticate this using some scripts, see the man of ssh and
ssh-keygen.

Now, externalserver listen on localhost:5022, and forward that to
localmachine:22.

On the externalserver, you can now connect to your localmachine :

  externalserver$ ssh -p 5022 localhost
  localmachine$
