Question
An ACK scan does not provide in order about whether a target machine's ports are open or closed, except rather whether or not access to those ports is being blocked by a firewall. If there is no response or an ICMP "destination unreachable" packet is received as a response, then port is blocked by a firewall. If scanned port replies with a RST packet, then ACK packet reached its intended host. So end port is not being filtered by a firewall. Note, though, that port itself may be open or closed.
