You have '-s 192.168.0.0/16', I don't, it means you are only allowing
connections from 192.168.0.0 to 192.168.255.255, I am allowing them from
anywhere.

I am by no means a firewall expert, I just know what works for me. This
isn't really a Samba problem, it works without the firewall, you really
need to find a firewall expert, perhaps trying on the Ubuntu mailing
list might be an idea.

I do hope you fix this, but I don't think I can help further with this,
perhaps Louis has some further thoughts.
