Hello good people...

I have a big problem with a bunch of Hikvision "DS-2CD1323G0-IUF"s and model "DS-2CD2T63G2-2I"s. Most of them send RSTP stream to wrong IP address.

Code:
# getPreviewStatus

RTSP lib version is: 1.0.2 [19:35:54-Dec  3 2021]
Preview lib version is: 1.0.0 [19:35:44-Dec  3 2021]

max preview link:6 max playback link:1
chan_1 preview link ch1:1 ch2:1 ch3:0
       playback link:0
       record status:not record

chain  client_IP      play_type   stream_type  proto_type  date/time
chan1  172.16.8.8     preview     main stream  rtp_rtsp    2023-02-26 10:46:20
chan1  172.16.8.8     preview     sub stream   rtp_rtsp    2023-02-26 10:46:21

********ANR INFO:********
Channel-No  Stream-No  ANR-ID  ANR-Client-IP    Start-time

The cameras are on a separate VLAN and therefore a separate subnet (i.e 192.168.1.0/24) and the client IP should be 192.168.1.3 instead. The router's LAN address on the subnet is 192.168.1.1. Of course, since the client IP is not on the same subnet as the camera, it sends all data to the router, and this is causing saturation.

I think I know why that happened. The Hikvision NVR (model DS-96064NI-I16) has 4 ethernet ports. LAN1 IP address is 172.16.8.8/24, and is the one that it uses to access the internet. LAN2 IP address is 192.168.3.3, the one that is supposed to receive video streams. I personally activated some using the SADP tool, but my friend did it on the NVR, and for some reason, the cams got the wrong client IP address and now I must find and reconfigure the problematic ones. My problem is that there is no such option in the web interface and I don't don't know how to do that using SSH.

I tried downloading configuration file, thinking I could find one that is configured correct and edit it accordingly and then upload to the others, but it won't let me have it in plain text.

Is there a way other than hard-resetting the cams?
