stun server. (just want to clear my concept)
i know this is not a right place to ask this question but it is just a concept clearing query. if appreciate any comment but since i only use debian as a whole solution i could not stop my self throwing this question. please ignore if you don't like to answer. actually i am looking in to installing Jabber XMPP server on Debian (openfire) and just i was doing my normal RD and i eventually end up on a option where it needs stun server. for voice and video communication. i know what stun does but i have a question to make thing more good conceptually. please correct me if my concept is wrong or worst about stun :P stun server is mainly used for Voice and Video due to their UDP in nature. so that if UDP recipient want to response back with voice or video packet it returns back to Stun and stun route back to our local server. but the question is why?. if i have a public Ip which is published behind example.com and i have all the necessary port forwarded to the jabber server so the recipient end could send its response to my public IP rather then stun server and in my opinion it should work as all the ports are properly forwarded. secondly, cant we use VPN as a substitute. where routing would be properly done. and no need to relay on public stun server? is there any one like to explain.

Stun servers do not perform any routing. All they do, is let your computer know which IP and port number it's using (as seen from the other end), so it can tell the other end, which IP and port number to use to contact it back. In your case, *you* might know these things, but your VOIP program probably doesn't (unless you manually tell it).
