Ok, so here is my situation. I am trying to gain remote access to a DVR camera system. I opened the ports on the router and pointed them to the camera DVR (192.168.0.100). I have used multiple port checker utilities to test the ports, and they are not open. Here is what I have as far as equipment.
ADT camera DVR model DRC-HD400
D-Link DIR-820L Router
Windows XP PC
DVR is wired directly to the router
I notice that on the router when I check the status tab, instead of a public IP address, I am getting a private IP (192.168.1.3). I put the DVR into a DMZ, I called the ISP and had them disable DHCP and NAT on their end so that the DSL modem is in bridge mode. None of this is working to get me a clear path to the DVR. When I check ipchicken.com it gives me an address of 72.xx.xxx.xxx. I can ping this address, however I can not open ports. Any help or ideas would be appreciated.
