I have been fighting with two DCS-2132L cameras and an Airport Extreme trying to do some off-site backup on a Sinology NAS.
Let me explain, at work I have two DCS-2132L cameras which I'm not able to see from home, where I have a NAS that I want to use to record. The cameras are set as follows:
Camera 1: http port: 80 - RTSP port: 554
Camera 2: http port: 1030 - RTSP port: 1040
On the Airport Extreme router I forward the following public ports to the internal fixed IP address for Camera 1:
public port: 80 - private port: 80 (both TCP for http)
public port: 554 - private port: 554 (both TCP* for RTSP)
And for the internal fixed IP address for Camera 2:
public port: 1030 - private port: 1030 (both TCP for http)
public port: 1040 - private port: 1040 (both TCP* for RTSP)
* I have also tried using UDP instead of TCP, without much luck**.
For Camera 1 using nmap I can see the ports are correctly set:
Nmap scan report for 10.0.1.202
Host is up (0.013s latency).
Not shown: 997 closed ports
PORT STATE SERVICE
80/tcp open http
443/tcp open https
554/tcp open tsp
And same for Camera 2:
Starting Nmap 6.47 ( http://nmap.org ) at 2015-11-03 14:57 CST
Nmap scan report for 10.0.1.201
Host is up (0.0100s latency).
Not shown: 997 closed ports
PORT STATE SERVICE
443/tcp open https
1030/tcp open iad1
1040/tcp open netsaint
And this are the ports that nmap find for my external IP:
80/tcp open http
554/tcp open rtsp
1030/tcp open iad1
1040/tcp open netsaint
I reckon this has to do with the RTSP port probably not being set correctly either on the camera or on the router, as I'm able to access the cameras using a web browser, so the http port is being forwarded correctly, but in the "LIVE VIDEO" tab where the video is supposed to stream I'm not able to see anything. And on my browser I can see the error: "Failed to load resource: the server responded with a status of 500 (Server Error)", when looking at the browser's console.
So there are a few questions:
Does RTSP needs another port to be forwarded/opened?
Does anyone has any experience with this kind of setup, and have it resolved?
I would really appreciate if anyone can please provide any insight.
Both cameras are using the latest Firmware version at the time of this post which I believe is 2.11.00.
