best external security camera image
octane
The remotely viewable security camera system at my business requires that I enter the ip address for access. Since I installed a wireless router to my modem, the ip address won't let me view video surveillance. Going to "What is my ip address" gives me information that is not relavent to the DVR.

You can try clicking start then run which would be the bottom right of the start menu and then type cmd in the command prompt type: ipconfig/all and that would display your ip address which is usually the first one that comes up. I hope that helps, if not the IT suggestion would work to. To find out the external ip address which is usually assigned by the ISP you can trying typing the "nslookup" command in the command prompt as the one above. I think that command gives the external IP.

How do I find out which ports are open on my network?
DPUCCIO
I am trying to use port forwarding to view security cameras over the internet. My camera system, using DHCP, has an IP address of 192.168.0.100. The data is set to come out of port 1026. The camera system is plugged into a hub with an IP address of 192.168.0.1 (set statically). That hub is, in turn, plugged into a DSL modem (which can also work as a Wireless Hub/DHCP server) with the internal address of 192.168.0.2 and an external address of 71.38.68.47. Internally, I can see all devices on the network whether I am plugged into the hub or have linked to the wireless modem. I have set port forwarding on the DSL modem to forward 192.168.0.100 port 1026 for both TCP and UDP protocols. It seems like I have done everything right. I have set-up a similar arrangement in the past with success. But currently, I cannot call the WAN IP address of the modem : port number of the cameras and get the picture. Maybe it is in how the modem and wired hup are linked. Appreciate any help.

On the *nix box in question type:
netstat -anp | grep LISTEN
and it'll show you all the open ports.
From another box use the nmap program (find on Yahoo! search) to scan for open ports on your boxes.
