Greetings!
If you use TCP/IP as the only protocol, file sharings with NetBIOS use
port numbers 137 through 138. You have to allow traffic incoming AND
outgoing because the server establishes a reciprocal connection back to
the client. The same setup applies to all SMB connection like Samba of
several Unixes.
A good place to look for answers to questions like this is the RFC
"Assigned Numbers".
