I've been using Back to My Mac without any real issue for some time now. Recently, I got a new iMac, so finally have two Macs running Snow Leopard. I tested out the Wake on Demand feature when had both connected to the same network and it worked just as advertised. When I tried to access the iMac from a remote network while it was asleep, however, it didn't even appear on the "Shared" list in my Finder window. Any ideas how I can get this working properly from a remote location?
