What does betray mean?

Public facing machines w/ iptables off?

So if you want it hidden, you want it not to accept connections from other machines?
See what's allowed, then if you're not iptable savvy, install/run system-config-security.
Then do not permit connections to that port, unless you provide more info, like do you
Have internal trusted interfaces etc, you will be locked out.

Probably good thing you haven't exposed a possibly bad config.
