Hi,
I'm trying to enable access to an internal webcam externally, through a firewall. For complex reasons I won't go into unless necessary, the firewall forwards to a server running xinetd, which then port forwards to the camera.
The firewall has ports 8090 and 40001 opened, the manual stating these are the two required.
The xinetd conf forwards 8090 to the camera port 80, and 40001 to the camera port 40001, the former rule called 'camera' and the latter 'camera_image'.
Now - using debian and firefox browser, i.e. the java applet option, I can see the webpage but the image is blank white. (The same setup could see the image fine on the internal network.) Error message on page: "Loading java applet failed". Only the 'camera' rule is invoked in the firewall log.
Windows IE users select the ActiveX button and can see the image fine, and I note that now in the firewall log the 'camera_image' rule is now being invoked as well as 'camera'. The java applet does not try and use port 40001 for some reason, but I can't see any rejected requests for other ports.
Can anyone shed any light on this? I hope I've explained it well enough.
Thanks,
Jenny

What is the make/model of the camera? I know the one we have has a crap active x viewer and also a java one. But after a bit of poking around I found a url for the mjpeg stream which can be viewed using mplayer or vlc, it might be easier for you to do it this way?

Thanks, Adam.
It's an Intellinet IP Camera Model MNC-L10. If i could find the mjpeg stream that would be great - I'll read the manual some more for that.
Progress meanwhile is that i removed the awkward xinetd setup and the firewall directs ports 80 and 40001 directly to the camera. With firefox this throws a java overload error, but I'm now getting an image using Opera and java applet. I'm waiting to hear from active X users.
The camera is pointing at a horse who is about to foal at any second, by the way!
