Should I open UDP port?
There is no such thing as an "open" UDP port, at least not in the sense most people are used to think (which is answering something like "OK, I've accepted your connection"). UDP is session-less, so "a port" (read: the UDP protocol in the operating system IP stack) will never respond "success" on its own.
