kiwi, Did you mean port 5000 and 5001 on the client side? My 760 is also benind my home router too. I just open port 80 as a virtual web server only. I can still get it work anywhere except at my office protected with a firewall box. I had also open the DMZ for my DVR as well but still can't get it work from my office. Thanks anyway for your info.

No, I can't. I don't have the admin access.

I meant I've found no port other than 80 is established even I ran it at home where I can get the video shown in the box. Java console having no such socket error message as well. Nevertheless, I'll try zonealarm or ethereal anyway.

BTW, I tried a way similar by using netstat -n I'could only found port 80 is established to the DVR server. Also, whenever I got the blank white video content, the Java console keep showing message below login run First-login Error: java net SocketException: Connection reset Seems it cannot establish a socket instance

I don't think it's related to the active x installation problem. It is because it works on my notebook at home but not in the office which is behind a firewall (watchguard).

I have the same problem. I also suspect that it uses other port in addition to the 80
