I cannot figure out how to get access to the ticket. I am also not sure I am interested in yet another such account. I have more than enough accounts and subscriptions already spamming my mailbox. So I hope it is OK that I reply in this mail thread instead.
If I understand the discussion, it was a decision in an early stage of Fedora 21 Desktop development that it should not have a User Interface for firewall configuration. And I think this is the basic problem and mistake. I cannot see how usability and security can be achieved at the same time without it Even though it is not a server platform, you may still want to run server programs on it (typicaly for access by other systems on local network). I can think of (at least):
* a test or learning instance of any database server
* all sorts of file servers
* media streaming services
.. and they will all require the port where the server listens to be open.
I think a very simple User Interface for firewall configuration should be added. It could be as simple as just allowing for opening of specific ports. I also don't think it will cause problems. People can manage firewall(s) in Windows. Dont' assume that users are more helpless than they are (that is/was Ubuntu's mistake IMO).
(and as a final remark the security issue is close to NULL for al the people running FD21 in a virtualized environment or behind a router. They will have the protection from the host OS or the router. But some people still use various types of modems and not routers of course)
