Yes I looked in the box it came in and found more info....genius

my UPnP was disabled so I enabled it and something called multicast was also disabled so I also enabled that (was this ok??)I looked around in the page at the firewall info do I also want to turn that off ?? it says something about NAT & SPI it seems like i can turn them both off or just the NAT any suggestions?? also my brick is still on my LW .... i am so puzzled
