I'm going to ask a question that has been asked before, but I couldn't find it in the archive. So here it comes: Which ports need to be open in the firewall to let Samba function properly? I want to get a tight (read sercure)as possible rule set for this? I already found out that port 137-139 tcp/udp need be open, because these are used by a number of netbios services.
