Openfire online issue

Hi

I Have been using openfire to host my Jabber mix client. It has been working well through LAN and local emulators. now i have deployed JMC(JabberMix) to real devices (mobiles) so i am now connected to the internet, i need to use it log in as my server. I have been looking all over the net on how to configure openfire to accept connections via internet but found no clues. i have now obtain dns srv but cannot add them to the server side. any suggestion on how i can make it online and reacheble via JMC and other clients?
