Hello, i just got my D-Link AC1200.
May i know how to setup DVR (CCTV). Which one should i set virtual server or port forwarding?

Thank you

it seem there is some bug at the unifi D-Link DIR-850L router 2.12TM firmware release at 2019, Dahua imou Ip Camera Cloud Live Stream would Disconnect 99% of time, While LAN and Wifi Live Stream still working 100% of time, but 6 Models, 4 Brands of newer and older generation Ip Camera Cloud Live Stream would still working well 100% of time.

tried to reset and reconfig/setting manually without config backup and upload unifi D-Link DIR-850L router, bug issue still happen.

tried to Enable UPnP: ; IPv4 Multicast Streams: ; IPv6 Multicast Streams: ; Application Level Gateway (ALG) Configuration ; PPTP: ; IPSec (VPN): ; RTSP: ; SIP: ; and Multiple Port Forwarding, work a while and Cloud Disconnect again.

Enable DMZ: work but didn't spend the times to test it for how long, but DMZ work for only single device/IP.

Tested Dahua imou Ip Camera Cloud Live Stream with TP-Link Deco M4 v2 Latest Firmware 190917 , working 100% of time.

the D-Link DIR-850L international firmware doesn't have TM TR-069 and other customization, router web interface is much smoother.
