I am trying to get external access to my HikVision NVR.
My provider is Comcast, which goes to my cable modem, which goes to my router, which goes to (1) A VOIP unit, (2) the NVR and (3) my PC.
I had to set up port forwarding for the VOIP unit to work. That works fine. People can calll me.
I set up port forwarding for the NVR but no dice.
Here's the strange bit. I used http://www.yougetsignal.com/tools/open-ports/ and http://www.whatsmyip.org/port-scanner/ to check both my external IP address (Which I can ping) and to check the open status of various ports. Both sites say all my ports are closed. Not just the NVR ones (80, 554, 8000 and 8200) but also all the port used by my VOIP device (Which are big ranges BTW, so there's no knowing which are actually listening...)
Further tests:
My NVR is set to a static IP. 192.168.1.122
My router has that IP set aside in it's DHCP list and sees it.
I can go to that IP and get into the Hik web access, so I know Port 80 on the unit is listening.
If the VOIP unit wasn't working, I'd be suspicious that the cable modem wasn't bridging the traffic. But it is working.
I have tried disabling UPnP in both the Hik setup and in the router.
I don't have any DDNS set up.
