So do I.
Helpful hint: with some of those, you can't actually switch off the
remote telnet; the device wants to either handle it itself or forward
port 23 somewhere. But you can forward port 23 to a non-existent host on
your local network, which has the same effect.
Consumer grade network devices: they're all the same, yet all suck in
their own weird and wonderful ways...
