I consider myself a slightly more then an average user, but not anywhere near to be enterprise/business user. I simply have 6 IP cameras that I need to port forward 3 ports for each cam (HTTP, RTSP & Server) That's already 18 port forwards! On top of that I need to port forward my pc, nas, so I could get by with 20 port forwards, but 15... All other comparable home routers from Asus, Netgear, Linksys allow more then that, why did Dlink have to limit theirs?
