【閒聊】請問有先進能解釋UPNP和DMZ的作用或不同嗎?

最近剛買IP分享器常看到這兩個名詞!
不過不太清楚實際上的作用或運作方式是什麼?
說明書有又跟沒有沒什麼兩樣!所以上來問看看!知道的先進麻煩了!!謝謝~

DMZ:All port on router will mirror to your computer(1IP=IDMZ)
UPNP:Can change the router by windows(e.g.When use netmeet the winxp auto to open the port on router)But UPNP have many problem,don't use is good.

那UPNP是只在MSN NETMEET這種微軟自己開發的程式上才有用?
還是我不開DMZ!其他程式有需要時也會透過UPNP自行開PORT嗎?
