I have taken the plunge on a trial for .Mac, however I'm having trouble getting back to my mac working. I'm using an Intel iMac connected to a Netgear DG834G router via ethernet, along with an Intel MacBook. I've enabled back to my mac and screen and file sharing on both Mac's and back to my mac works fine when I'm in the house on the local network. If I am using the MacBook away from home on a wireless internet connection then my iMac won't appear in the finder sidebar at all. A look around Apples support site suggests using an Airport base station but it's quite expensive and doesn't come with an adsl modem. Also it does not list the Netgear DG834G router on the list of tested devices, but it is still UPnP enabled so I can't believe that it is the sole cause of the issue. Any help or suggestions greatly appreciated.
