Named ports are called "netbios" in some tribes. It was a good choice
to block them anyway. I cannot say what it means on the linux node,
except for samba.
After a little experiment above, it looks obvious that device gets ip
address in a dynamic form. It takes gateway and fires up it's client to
connect kobo server. I would rather run tcpdump or some other app
for network traffic logger and see what's going on on the wire.
I'm not sure what win apps could see on ports. For any further job,
nmap should be considered. Server, waiting for connection, makes
port open. Filtered port from time to time means there is a firewall
involved. Not always. Have to confess I do not understand win termi-
nology.
I'm quite interested in topic like this, spite I haven't wifi device.
