Hi FurryNutz, thanks for reply and your help.
My DNS model is DNS-320L, and its hardware version is A04. Firmware version loaded is 1.08 taken from this forum. I think my region and mfr/model of my router and ISP modem are all irrelevant for the issue, since freeman74 has the same problem...
I can access to the Surveillance-Station add-on and see my DCS-5222L camera working ok, but only from inside DNS320L user interface. I mean, I have to do the following:
1) access to my DNS-320L via its IP in a browser. (My DNS-320L is setted with a fixed IP)
2) login in my DNS-320L
3) Once logged, go to "Surveillance Station Aplication Add-On"
4) Then, it opens a tab with information about that "Surveillance Station Add-on" and offers a button to "LAUNCH" the aplication...
5) So, I click that "LAUNCH" button, and then opens a new tab in browser with the main interface of the Surveillance Station
As I understand, maybe I'm wrong, the purpose of those 3 ports (Live Video Server Port, Playback Server Port, and Configuration Server Port) offered in Server Port section, inside Setup configuration page of SurveillanceStation, is to offer a way to access directly to each main interface of Surveillance Station: Live Video, Playback, and Config, respectively. So that way, we would be able to get access to the Live Video panel without making the five steps before, and getting it asking only http://192.168.X.Y:<live-video-server-port>....But the problem it is not working. And I have already tried open those ports, both, on my router, and on my DNS-320L configuration...
Related with this issue, I've tried out with "Blog add-on" (actually a wordpress), I installed it and I get an expected behavior: I can reach "that wordpress" directly asking http://192.168.X.Y/wordpress, without any login first in my DNS, nor "launching it by clicking a button before"
Thanks for support
