Per the notes, please make sure your users in the ftpusers file DO NOT HAVE THE SYSOP_CMD bit set. If you also set the password, then anyone trying to access can't get in without it.
What Rob was saying, however, is that many run both FBB and JNOS together. If you were running FBB with the gateway feature on so that say I could use it to get from your FBB to your JNOS, I would appear at your JNOS as YOU not as ME. So, if I connected into your JNOS, I would (via your callsign) have the sysop flag set, and if I had any possible clue what your password may be I could try that and gain full access to your box.
The "gateway" feature in FBB is something the sysop can flag on|off on FBB. I believe the initial design of this feature was for the sysop to manually test his/her forwarding script before etching the path into stone.
