Look at your last post here at the bottom just after where is says report to moderator. That is the IP address you need to use.
Ha interesting I never would have thought of that... I was going to have him use ipchicken.com

You might want to look at a service like no-ip.com if your public "global" IP changes alot. Also once you get this setup a little more permanent the 10.0.0.2 that's assigned to the laptop you might want to make that static and assign an IP address outside your DHCP scope.
Regarding you other question about port forwarding.
Most routers will not allow traffic to the outside and back in so test your port forward from a cell phone connected to 3G or LTE.
I have 2 icons on my Iphone one called "MFI Remote" and one called "MFI". The "MFI remote" points to flaughs2000.com:6443 and "MFI" points to 192.168.78.4:6443 to get around this problem.
Also if you get into a bad bind we can schedule a phone call and work some of the kinks out.
