Asus Router Port Forwarding Confusion

Looking for guidance on setting up a security camera recorder for remote access via DDNS URL that you can sign in to. This is basically where you have a URL that you can log in to from a web browser to view the cameras over the internet. The camera manufacturer has their own servers they provide to run all this, but you have to set up port forwarding on your router. The router is an ASUS RT-ACRH13.

Network Video Recorder (NVR) device is connected to the router. Windows 10 PC is hooked up to the router. Router is hooked up to the cable modem for internet access. Here's the info on the NVR device:





Here's what the port forwarding screen looks like in the router settings:



Any one know what I'm supposed to enter in the External Port and Internal IP Address fields? These are mandatory fields.

Thanks.

 

Did you put static IPs on the NVR?
In the router you forward the external port to the local port on the assigned IP address. That is why you static the IP on the NVR, so it stays on the IP you forward to.
The external port can be *anything*, so you can "hide" it on an uncommon port..9090, 1919, as long as it is forwarded to the correct IP & port on the device.
Do you have the router updating the DDNS?
Say you set the external port to 8080.
In the router set the external to 8080 forward to internal 192.168.50.77 internal port 80
You can make the external port 80, but people scanning would check that port for sure.

The using a DDNS, name service you would go to www.yourname.com:8080

 

The 2nd screenshot has an option for Static or DHCP. Should I change it to Static?

I'm not sure what that means how do I connect locally? There's a few different IP addresses I see around and confused what they mean, but none of 'em seem to have any :8080 type syntax.

I'm not familiar with what "external port" and "local port" mean. And not sure what that means to have the router updating the DDNS?

 

Here's a video that gives an explanation. But the problem is, my router (the same model in the video) has a different looking screen. and different terminology:



So I'm not sure how to go from what's in the video to my different-looking screen.

 

In your original statement "for remote access via DDNS URL" I assumed you were using a DNS redirection service, are you not? A "Dynamic" DNS service is where you set up an account and make up a name for the URL. Then usually somewhere in the router you have the option to update the DNS service by entering your URL, name and password you set up with the service. So you can open a browser and go to www.thisismyurlname.com. Assuming you don't have a static IP from your Internet provider.
The NVR should be static or it could get a new (different IP) when the lease ends or you reset the device or router. External means from the Internet basically, Internal means specific to your local network. You can make IP reservations on the router (so click the static option)
So these steps should work if you plug them in your router:
In the router set the external to 8080 forward to internal IP 192.168.50.77 internal port 80
You can make the external port 80, but people scanning would check that port for sure.
The using a DDNS, name service you would go to www.yourname.com:8080
Without a DDNS, go to whatsmyip.com, use that ip in your browser with the :8080 and you should see the NVR log in.

 

Yes, I setup an account with the NVR vendor through their website and created my own URL that I named. I went ahead and set External Port to 8080 and Internal IP to 192.168.50.77. But now when go to my URL that I named, it doesn't load. I'm using a website to test port forwarding https://www.yougetsignal.com/tools/open-ports/ but no matter what I do, it keeps saying the port is closed.

 

What happens when you open a browser and try http:\\192.168.50.77 ?
Did you add :8080 when you use the URL that you registered?
Did you try going to whatsmyip.com, use that ip in your browser with the :8080?

 

View attachment 238512 By trial and error, it looks like I finally got this thing working. I can now get to the URL and sign in and see the cameras. It actually took 2 entries to make it work:
