I just purchased a D16CS DVR for my hotel. It currently is on the network and setup with a 1:1 NAT. All ports are open. I'm told by my IT person that if I enter the IP address that he has given me, I will get the DVR.

I've was told by the not-so-helpful Speco tech support that I have to forward the ports but on a 1:1 NAT I shouldn't have to do this.

I'm using the Specotech ddns service that is provided but I can't seem to connect off-site. The web address that I'm told to use is [Link: ddns.specotech.net]).

Is there something that I'm missing?

Thank you for your help!

You will need to do the port forwarding. Very simple to do, but depending on which router you are using.

I'm confused, if I already have a 1:1 NAT, why would I need to forward the ports?

With full 1:1 NAT you would require an external IP address (from your ISP) to point to every single device located inside your network - so no sharing. Is this the case? What router are you using, and how has it been configured? It is usually still possible to block ports on 1:1 NAT, and you may still have a firewall layer to get through.
