Hi all , I have my new DVR cameras system , also I have my Public IP address , just have a look to the DVR system ports and my setting in my router ..








and this is my router settings





also i put dst port 8000 and in action to port 80

now if i try to use my Public IP address to get access online on : http://xxx.xxx.xxx.xx:8000 , the Mikrotik is forwarding but i couldn't get online view ... my ask is there another setting should i do in my router or my DVR ??

You also need to allow the traffic to the DVR's address in the forward chain.

You also need to allow the traffic to the DVR's address in the forward chain.

can you tell me how please

Add a filter in IP / Firewall / Filters. It should be on the forward chain and specify the dst address / port as that of your DVR. Set the action to accept. You can also further limit the filter depending on what you want to allow.

If you don't know how to make firewall rules in routeros you can enable UPnP.
I see that you DVR supports it.
Enable it in routeros IP -> UPnP, put check mark on Enabled and in Interfaces add which is your internal and which is external interface.
