I have a multi-functional machine which is both a laser printer and a scanner (Samsung SC-4705ND)
I am not able to make the scanner work with the (software) firewall installed in my computer turned on. Operating system is ubuntu 12.04 with regular firewall.
if firewall is turned off then everything works as expected
I run nmap to discover open services on the samsung machine and I opened all these ports:
80, 427, 515, 631, 5200, 9100, 10001
but with not luck..
How should I configure firewall?
