Trying to port forward through a Cisco DPC3825
Hi, I recently got a Dlink network video recorder for my security cameras and I am trying to forward the IP of the NVR so I can access it through the internet. I have followed the tutorial and looked at posts here and had no luck. my PF box is attached to a Cisco DPC3825 which I believe maybe the problem for me not being able to reach the NVR. I have placed the PF box in the DMZ on the Cisco modem/router, but had no luck getting through to the NVR. Are their any further steps I can take to make this work or am I out of luck.
