Remote Desktop Help

[Racincason]

Ok guys, i need some help. You guys are some of the smartest people i know. So here's the deal. I have a problem with connecting to my computer when im not on the same network. As long as im on the wifi network that my computer is on then i can connect no problem.
So here's what i got

Im using a router and so the router has a different ip addy for the computer than the computer actually uses.

So for example my router has my ip address as 192.168.0.2 and when i go to say ipchicken it says 67.41.247.8 I have already told my router to open a port for it but when i go to connect it just times out.

My question is for the host do i need to have 192.168.0.2/67.41.247.8 and for the user do i need to have the usernameofrouter/usernameofcomputer and rouerpassword/admin password? im just having a heck of a time and i have looked through everything i can think of. i know someone out there has it working and i just wanted to know how!!!! Any help is appreciated!!
