I've mroogled and googled around for this and haven't really found a definite yes or no, so hopefully i can get an answer here for sure. does back to my mac require you to have a public IP? I know how all of the port forwarding crap works etc, i understand people having problems with the nat redirection and upnp not working. however if back to my mac needs a public Ip, then that's what most people are having trouble with. I can easily setup an autossh bash script to tunnel the required ports to a public IP. I'm about 500 miles away from my mac mini server right now, and totally forgot to start a job i had setup before i left. back to my mac is turned on but I'm not having much luck with it. I can ssh (remote management), vnc (screensharing), and afp into the computer all day long from within my network. and both of the macs i'm trying to use are logged into mobileme (they've been fighting over widgets all day, which is starting to get on my nerves. i'm about to have to reset the widget data on the mobile me server again). if back to my mac requires a public ip, that's what my problem is. the mac mini doesn't have a public ip (ie; the router it's connected to doesn't have a public ip). I have a public ip where i am now though, so i'm sure my mini at home can see me. I'm about to be finding another use for my linux box. if i have to sit it somewhere and run a vpn/ssh tunnel so that I can use back to my mac and everything in back assed way, then i'll go that route.
