ok so i was recently trying to forward port 8016 to the internal host of 192.168.0.100 and prior to installing my server, all this was working fine. The host is a DVR, which im setting up again for remote access and viewing, the problem ive got is, the host wont accept connections and the port wont open, and so i thought id check the server to be sure that nothing was stopping it, no NAT config or routing issues and found the following

The DVR is on 192.168.0.100 and the "internal" device on my server is also on 192.168.0.100, so im assuming that port 8016 is forwarding to the internal device on the server, atleast thats all i can think it is.

I could rectify this pretty easily, just change the ip on the DVR, but i was just woundering, what exacly is this INTERNAL device and what does it do, being new to servers, and having set this one up purely for experiance and to learn, i may aswell learn as much as i can. Below is a screenshot

Thanks for any help on this topic in advance!!
 
The internal network is the part BEHIND your server, in other terms, your secure network (the green cable) in most cases you have also an external network which is considered unsafe (the red cable).

What I don't understand is how your network can operate if internal interface has the same ip of your DVR...
 
Well id say the dvr just isnt communicating. Can i change the ip on the server

However in saying that, local connections were fine to the DVR, just not remote as i take it it was forwarding 9016 to the server not the DVR
 
This could be correct, when your server routes the external connection, it stops at 0.100 which is the internal IP. You must change the ip of your server or the DVR.
