My problem is when I have router in local host, my client works fine, but when I move router to an other computer, then creating topic connection gives me error like: error creating socket connection to 127.0.0.1:14001, message: Connection refused: no further information
(I use port 14001, in local host it works). Why does it dry to connect to localhost? If I put up router in localhost too, it starts sending messages to this one!?
Anyway maybe this problem might have something to do with changeing the router version (swiftmq1.0 to 2.1.2)?

Could anyone help me with this one, I'm in big hurry, router and client should work on monday :-(

Thank You!
