Hi,

You will need to ask another server to tell you your public address. Maybe this will help you:

public string getPublicIP() 
{ 
    string direction; 
    WebRequest request = WebRequest.Create("http://checkip.dyndns.org/"); 
    WebResponse response = request.GetResponse(); 
    StreamReader stream = new StreamReader(response.GetResponseStream()); 
    direction = stream.ReadToEnd(); 
    stream.Close(); 
    response.Close(); 
 
    //Search for the ip in the html 
    int first = direction.IndexOf("Address: ") + 9; 
    int last = direction.LastIndexOf("</body>"); 
    direction = direction.Substring(first, last - first); 
 
    return direction; 
}
