Explain more about your setup.
it's on localhost?
did you forward your ports correctly?
Can you connect to your server via dayz client?
did you check your firewall config?
i know gamingdeluxe uses this: http://ibattle.org/ but i can't get it to work yet.. (some weird error about not begin able to connect even when the local ip and password is correct)
I think they use an older version of it, but im not sure about it.
