On a properly configured system basically the average desktop should
have little to no services listening and those that are likely are
allowed through the firewall anyway so aren't protected by a firewall.
Ultimately though we should likely offer a means to detect when on a
public or private network and bring up the firewall on the former to
protect the user as they're unlikely to want to share their dlna media
with most people on a public network.
Or have the services listening on the network be stopped.
