Hmmm, what IP address does your mac say that it is using? Did you configure your airport base station at all using the supplied software or did you just plug it in and start using it? Try setting everything up as I mentioned (but write down the current settings first) using configure via DHCP. Make sure that the empeg is plugged into the base station with your cross over cable before you plug the power into the empeg. Once you have done that go to the empeg's about menu and let it scroll until it shows you what IP address it is using and then let us know what that IP is. If this works you will want to leave everything setup this way while you use Jemplode (or emplode under VPC). What is supposed to happen is that the base station will provide an IP address to your mac and to the empeg. This will be from the same IP address range so they will be able to talk to eachother. -Mike
