What about reverse SSH tunnel?  I think it is what I need.  A public 
"relay" server runs a "standard" ssh server, so it will be very simple 
to delivery.

On my device should be running a ssh client that creates, with an 
outgoing connection, a permanent SSH tunnel with the "relay" server.

Now the end user can connect to the device by using the public "relay" 
server.

I think it should work, even if I didn't test this configuration. 
However the only problem is to implement a simple SSH client on lwip 
device... I think it will be a very complex task.
Anyway I don't need encryption provided by SSH... maybe a simple telnet 
tunnel should be sufficient. Is it possible?
