Firstly, you will have to know your external IP address (one given to you by ISP)
Secondly, you will have to forward some ports in your router to the IP address of your computer (the 192.168 one). I believe it will be port 5900+N and 5800+N (where N is the "desktop number", so if you "desktop number is 1, you'll open/forward ports 5901 and 5801 to your 192.168 address of you computer)
If you are not sure on how to forward ports on your router, check the manual or have a look online, do a google search for say "[router name] forwarding ports" or something similar
