Hello, I've just replaced my old mesh wifi router with a Deco X60. I'm trying to port forward my video system DVR so I can access my security cameras when not in the house. I can see my DVR on the list of devices connected to the Deco X60 and have set up my port forwarding rules that I know work from my previous mesh router. However, when I go to the video system app to see the video feed, it is not able to connect to show the feed.  The router accesses the internet through a Quantum Fiber C5500XK modem. Do I need to ask Quantum Fiber to change any settings on the modem? Or is the issue on a Deco setting? Any guidance would be much appreciated. Thanks!
