I need to forward a range of the ports, such as 27010-27040. On the AirPort Admin utility as show on the picture, it seems you can only setup one port at a time. Is there anyway you can setup a range of the ports at one time, such as specify 27010-27040? This can be done easily on popular Linksys or Netgear router, no luck so far on Apple Airport Extreme Station. Any suggestions? Thanks!
