Question About OS X Firewall....

in macOS edited January 2014
Just out of idle curiosity...

I have Brickhouse to configure my firewall, and basically just use the defaults (i.e. block all incoming, allow all outgoing). When I use Brickhouse, I find that when I check for open ports (using for example), everything comes back stealthed. However, when I just use the button in the Sharing Pref Pane, the scan indicates some unstealthed ports. Why the difference?

P.S. Wasn't sure if this was Genius Bar or not...

    Which ports are not stealth? Do you have any services turned on?

    Nope, no services at all.

    Usually its port 139 that shows as unstealth, and I know thats the one used for file sharing with Windows machines. Occasionally others too (and usually they're UDP ports).

    Maybe its nothing, but if I have no services on and the firewall activated shouldn't every port be stealthed? I guess I just don't see why Brickwall has to be used to get this effect. I know I'm probably just being picky, but I was just wondering.
