i think i can help you to come out from this problem, as i have done this settings before so  
  
many times, but i am afraid of only one thing that i haven't used this D-link's router yet,  
  
but dont worry i can handle it out. 
  
so can you please give me detailed reply so that i can go throught it and guide you . 
  
a) what type of camera you using ? (analog or ip-based) 
b) if using analog type , then wht type of device using for transmiting video on net ? 
c) is it confirmed that you can transmit this device's video on net ? 
d) what type of compressions you using ? 
e) the main thing, which PORT numbers are used when you view the camera's on net ?
