O.K. I'll try to decipher exactly what you are trying to accomplish.
Essentially, you want to expose your video server to the internet, is that correct?
You also want to be able to access your video server from your home network, is that correct?
What you want is a DMZ (google it).
Keep in mind and be aware, exposing a computer on your home network to the internet is not the smartest thing in the world to do, especially if you are exposing it with common ports wide open (http port 80 as an example). You really need to know what you are doing, which it sounds like you don't.
I will tell you this. Expose an improperly configured web server without proper safeguards and protection to the internet, and I estimate that you will be lucky of you don't have some kind of intrusion or attempt within 5 minutes.
