Unhappy Locking Down Ports...


Just ran nessus on my system and found a bunch of things I wanted to close up... But for some reason I can't...

The following ports are always open and giving out information even though I have them closed and dropping any connections via my firewall...

53 (BIND)
123 (NTP)
137 (NetBIOS)
139 (NetBIOS)
515 (Printer)

What got me nervous about all of this was that Nessus was able to get some nice info off of my Samba server, like names of shares, my workgroup, and the other computers on my network...

My firewall is set to drop any connections from the internet to those ports, but they still continue to leak information...

Anyone know how to kill access to these ports without killing the daemons running them (b/c I use them on my local network)?
