depending on the version OS your flowpoint runs, you can limit what ip's
can telnet in using the filter command.  if you apply that feature
correctly, you effectively prohibit brute forcing the router pw.  treat it
like cisco's access-list's retarded little brother and you wont be too
disapointed.

Well, adding a short delay in the code which authenticates the password
would make brute-force pretty painful and time-consuming.

true.. adding a 5 second delay might make it take longer but the attack
might well still go undetected unless one is in the habit of checking the
system history on the router, and i doubt the vast majority of flowpoint
owners do this.  ultimately, delay code might turn a 1 day hack into a 1
week hack, but it probably wont stop someone dedicated from getting in.
id say the most efficient solution is the filter still.
