Ok. I installed Leopard on my work G5, and also installed it on my home MBP (two separate copies). I enabled "Back to my Mac" on the work computer, but now that I am home I can not see it. I enabled all but the most RIDICULOUS sharing options (seriously, an unsecured http address? That's crazy). Why can't I see my work laptop at home? I am pretty sure that port 5900 is not being forwarded. Is that the cause of my problem? Any thoughts appreciated.
