Public bug reported:
Binary package hint: gufw
When you add the cups exception rule the using the predefined service
in gufw the rule "631/TCP allow EVERYWHERE" is added. I believe that
the correct thing would be "631 allow everywhere" which means it can
allow both TCP and UDP protocols. This is needed because in many cases
printers broadcast UDP messages to inform the computers on the network
that they exist.
I am not sure about this, but I have come up to this conclusion watching
the listening ports of my computer and capturing packages with
wireshark.
