Well, one's IP is logged by pprune so the admins here can find it
Anyway, I wonder how you would get in from the outside, via a NAT router.
I don't think there is a way if you don't have any open ports and assuming the router has no back doors.
Obviously if you con the punter to run software of your choice (a trojan) then all bets are off again but I don't think one can break through NAT.
What would you spend a couple of hours doing? Run a dictionary attack on the router's admin port, 443? People do that all day and all night on my office server... but ours isn't open.
Keef - are you sure that having c: closed and d: e: f: etc open is secure? Doesn't Windoze ever execute anything on other drives? Let's say somebody placed a specially corrupted desktop.ini file in one of the folders?
