There is nothing difficult in setting up a SSH server. I'm responding because you want to secure it on MAC address. It would be a less-than-minute hack. Allow login for only one user (and restrict su only to that user), not based on a dictionary word with a strong password and you are fairly safe. Additionally you can restrict access to the IP range your DSL is in, but this is really not essential.
