[Samba] ipchains question

Hmm... That's interesting.  I started out with the firewall blocking
everything and then slowly allowed in ports based on what was being
logged.  I did check the rest of my policy to make sure that it wasn't
listed in a different place and it's not.

What I have is completely functional as far as samba is concerned,
although I should have moved port 443 to a different section in my
policy.  This server has been up and running for quite a while using the
above iptables policy.  I bet if you try it, even with logging
everything that gets dropped/rejected you will find that it isn't using
the other ports you mentioned.

Anyone else have any experience with this?

It looks like you still need to allow port 137 on TCP, 138 on TCP and
on UDP.  Oh, and 443 is for https.
