Problem accessing DVR through ASA

baskervi · ‎03-08-2012

We have an ASA-5505 running 8.2(1) with a Bosch DVR 600. When a machine is on the local subnet, it can see the video; however, when it's moved to the DMZ, the unit can be accessed, but all video screens are black and an java script error pops up as follows:

[][]http://<IP>/cgi.js[][][],[]16[][][][][][][][][][]'AjaxClass' is undefined

This message does not pop up when on the local subnet. Additionally, in the login screen, there is a language selection, and sometimes all languages are blanked out. There is a space for them, but they don't display.

I've tried this on a half a dozen machines, either XP or Win7 with IE8 and IE9, and they all do the same thing. I disabled http inspection, but that doesn't help. I also did a packet capture, and the only packets that traverse the ASA are http.

I'd be very grateful if someone had an idea of what I can try. Thanks

I have a little more information. After doing a packet capture this morning, the following is happening. The session is established, login to the website occurs, my system closes the connection which is ack'ed by the server, then my system reopens the connection. This is repeated over and over. The crazy thing is, I can put my system on the same subnet as the DVR, and it works fine.
