Security DVR to Internet?

Can you answer fuze’s question about Surveillance?:

Trying to connect a security camera DVR to the internet.

I’m a bit confused. I’ve entered my IP, Subnet mask and Gateway as it appears in my router configuration (and the data sheet provided by the ISP). This is not working.

My actual IP appears to be different when looking at “Find my IP” sites online (172.16.**.** vs 24.155.***.** ) Could this be a problem?

I know my question isn’t clear, but it’s a bit much to type.

Thanks
