Ok, I'm assuming you want to connect to your laptop at home from your phone using RDP. If that is the case this is what you need to do. Log into your router and find where is allows for port forwarding. It may say just that or it may be under Firewall, or applications and gaming. Each router is slightly different. Once you find it you need to forward port 3389 (TCP) to the internal IP of your laptop (i.e. 192.168.1.XXX) Once you do that save it. Then on your laptop, make sure you have Remote Desktop Enabled. Once that is done, find what the outside IP of your router is (you can go here,
www.ipchicken.com_ and it will tell you. the on your TP2, open up remote desktop, enter the server IP, and user name an password (your computer must have a password or it will not work) and hit connect, you should then see your desktop.
Hope this helps.
