NVR not doing address translation this morning

[Robert Franz]

I am setting up a system for some folks - was remoted in via vpn and connected to the NVR web interface, while also bouncing to SmartPSS to review video.

NVR address is 192.168.40.30 - cams are 10.1.1.65-69 ports 10081-10085

All addresses static.

On the Registration page, links have always been in the format 192.168.40.30ort.

Now, all of a sudden the links are just the raw internal address.

I assume the NVR normally either nats or port forwards.

I tried removing and readding a cam, as well as rebooting.

Cams are still fine as far as viewing them from the web interface, though SmartPSS is borked now.

I was going to go onsite today anyway.

If I connect to the switch side of the NVR with a laptop, will I be assigned an ip?
Right now, sniffing the traffic is the only idea I have.
Anyone seen this?

reboot the NVR and your router for a start.

reboot the NVR and your router for a start.

Already rebooted the NVR - not going to reload the firewall unless I see a specific indicator.

What seems to have worked so far is deleting the cam - and then waiting for a while before readding it.

This is interesting.

I removed another cam, and was waiting to readd it - when it was readded on it's own and was back to the problematic link.

I'm going to remove the rest just for giggles.

 

[Robert Franz]

Ok, this is kind of amusing.

I removed the cams from channels 3/4/5.
Waited a minute - then readded just channel 3.
4 and 5 came along for the ride, and the links are correct on those - still just linking to the non routable ip for channel 3 which I did explicitly add.
Note also how the port column is displayed.
It's just as useless as displaying 37777, but slightly more informative.

Assume that NVR has built in PoE. Remove the ones that show a port if 37777 and as you saw let the NVR add them, don’t add them yourself from the top pane or they’ll get the 37777 port

 

[Robert Franz]

Removed channel 3 - did not readd, but exited the screen and reentered instead.

All is now normal, other then the ports displayed differently, and all the added cams in a state where I can't deleted them.
I would have to add them before deleting.

Weird.

 

[Robert Franz]

Does it matter?

Just trying to grok what's happening under the hood.

I always assumed the 37777 was just an extraneous display bit, sing the cams are not on that port, the nvr is.

I go ahead and readd and delete them.

 

[Robert Franz]

All appears normal now.

Would this explain why the camera ports have been jumping around?

I would open SmartPSS, and all the camera ports would be wrong.
I thought I had just mixed them up until about the third iteration.

In any case, thanks for the assistance!

 

[bigredfish]

Glad it worked out.
Not an expert but 37777 is the comm port for hitting the cameras normally from external. The PoE switch built in doesn’t seem to use it, thus unlike a non PoE switch NVR, best to not manually add cameras, let the NVR add them itself and it assigns the Port 1,23, etc

 

[Robert Franz]

I went with the poe version with the thought of extended poe plus the higher per port wattage if they want to add a ptz with a built in heater.

I can't believe how much time I've piddle away though tweaking things.

Doesn't help that the guy who will be using this is illiterate - I don't mean that as a slur - he literally cannot read or write much beyond his name.

So I can't give him written instructions or cheat sheets like I normally would.
