I am not a networking expert, but these are simple questions that any good network technician can answer. Basically, NVR/DVR is an IP device just like an IP camera. The same procedures would be required to be used. Depending on the OS used in the DVR /NVR , the settings would vary. Nothing too difficult for any good Network technician. Basically, if it is an XP system, XP assigns specific port for specific tasks. These can be changed of course. For instance it is port 25 / 995 for POP3, port 465 for SMTP, etc. A good port mapper software will show the ports being used in the system. Routers use small routines to route traffic, they do not need OS. Managed switches ( Layer 3 and above ) use some kind of intelligent OS (?) to do many tasks such as load balancing, assigning traffic, following rules etc. As I said, a good network engineer would tell more than what I can. But, it is definitely not rocket science. With a few hours of study and friendly " Google Uncle", almost every one can configure basic network interfaces. I faced the same questions when I started on IP cameras way back five or six years. We consulted network engineers, asked "Google Uncle" and were able to trouble shoot almost all problems ourselves.

I suggest you look at www.portforward.com/router where you will find a very wide range of devices listing which ports need to be forwarded and then you can select from an equally wide range of routers to select the router in question to determine how to specifically port forward. We recommend all of our installers of Quadrox WebCCTV NVRs to this site.

Try turning on UPnP. Any network device or software worth it's salt will have UPnP service available. Of course your router has to support it too.

Beyond that, it comes down to knowing how to set up NAT and port forwarding. I would recommend using OpenVPN instead of port forwarding for any NVR access anyway. You really should have fully encrypted and authenticated links going into a surveillance network. Port forwarding leaves you exposed.
