I.e. it is instantaneous and does not require either a reboot NOR re-activating using ufw enable or ufw disable; ufw enable. In short, if you're not manually editing the iptables but leaving everything to ufw, then you should not need to flush the rules via a reboot or iptables -F. I hope that helps :-) As to why the neotv isn't seeing the samba server - this may just be that you've omitted to allow one of the multitudinous (*insert rant here*) ports required for windows networks to operate. -- Daniel Llewellyn
