streaming flash media server to the world and not just your local network

hello, i have downloaded and installed flashe media server.....but i have som problems which are: i am on a network which is connected to the internet and i was able to get the ip of my pc using the comand prompt (i.e typing ...ipconfig/all....in the comand prompt window) ...i used this ip in my flash media encoder in place of "localhost" in the fms url, and i was able 2 connect fine ,i the copied my fms url to the osmf player and i generated my html code and put it in my webpage and everything did work fine, but the proble is that only the people who are on thesame network with me were able to view the video on the webpage wereas people in other countries could not view the video....... so please how can i be able to make my video acessable to the whole world ,because i work in a television company and they have asked me to undertake the task to stream thier broadcast online to the whole world........please i would like u to put me through the right things to do because have been having sleepless night on flash media server.....would be expecting a reply from anyone who can help me as quick as possible. thanks
