I hosed my router, and had to go back to an old one that could only
forward port 22 to an internal machine port 22. I got lots of brute
force attacks. Well, most of them only tried about 5 passwords each, so
not exactly brute force... Anyway, once I upgraded my router again and
forwarded port x0000 to port 22, I haven't seen one since.
