i have my iphone tethered to my computer using the 'official' way. i noticed that the computer is not given the internet ip address directly. it gives tethered devices ip address just like a router. either in the 192.168.20.2+ or 192.168.21.2+ range. is there anyway i can expose one of those internal ip addresses to the internet? i tried typing in 192.168.20.1, but that ip address belongs to phone itself (because if i'm running the ifile server, it takes me to it).
