Just bought the new Airport Extreme and was a little disappointed to find no firewire and only 1 usb. I need to join a G5, powerbookG4, external harddrive ,and three printers(wife is a photographer) on the network. Can I come out of the new extreme with ethernet into the old airport? If so, can(should) I run into common ethernet port to keep the same IP scheme? Any advice would be great!
