error trying to access cctv remotely

Balmed Out

Hi im trying to get my cctv system to work remotely. have it set up with a static ip address and i have it working to a degree. I get to the log in screen but when it starts loading the java applet it gives the following error message. This is happening from within my network or from the internet. The cctv system is an edr1600 so the edrwatch would be a class relating to it. Im suspicous its something to do with my netopia routers set up. This happens even when the firewall is completely off.

Java Plug-in 1.6.0_21
Using JRE version 1.6.0_21-b07 Java HotSpot(TM) Client VM
User home directory = C:\Users\Me

Speculative, half-arsed guesses then:

That suggests it's trying to open a HTTP connection to the local machine. You mention the IP there, but not any port number. Is that static IP the public facing one, or your internal one? Does that address open in a web browser? Is it then that it gives the Java error?

What firmware version is it running? Is it later than the one available here:

ftp://208.50.31.200/Product%20Firmware%20Upgrades/EDR%201600/3.3/EDR1600V33/

Thanks for the reply. I have the cctv system runing from 192.168.1.100 with the router port forwarding to it on port 80. I can get past the router log in and the cctvs own log in from both the internet using the static ip and my own network using 192.168.1.100. It then starts loading the java applet and just as i would expect the camera display to appear i get the error whether accesing from the net or my own network. The cctv system, when i try to upgrade software responds that theres nothing newer available. If i set the cctv sysem to 192.168.1.254 then it all works perfectly but obviosly only from my own network.

Is the netopia 192.168.1.254?
Can you do Nat on the netopia to the 192.168.1.100?
I would focus on getting it working internally before even looking at it from outside.

i did get it working internally on 192.168.1.254. its when i set it up on 192.168.1.100 with the nat from the static ip that i get a problem

If you put the 192.168.1.100 onto the CCTV DVR
Leave the router on 192.168.1.254

Then what happens when you browse to the DVR on 192.168.1.100 internally

If it works internally what you then need to do on the firewall rules on the netopia is setup a rule that fowards all incoming traffic on port 80 to the DVR address of 192.168.1.100 .

no it wont work internally then, will only work internally on 198.168.1.254 but then obviously internet wont work as sharing ip address and wouldnt be able to set up the static port forwarding. just threw cctv onto the static and tried using ip passthrough but that didnt work either though not surprising as ive not used before.
