So the application needs to ask the firewall to open one or more ports
and the firewall has to ask the user for permission to do so. In this
szenario the firewall knows what application wants which port(s) to be
open. Letting the application directly ask for permission to punch holes
in the firewall is IMHO the worst case of all and a securiry nightmare.
