They installed my new fiber internet and now one of my security camera DVR's can't be viewed over the internet. I can see it locally over the router wifi, but not on a cell phone app. I have 2 security DVR's and one works still and one doesn't. It's as if a firewall is blocking it, but I tried turning off the router firewall completely and still the DVR doesn't broadcast to the internet. My internet tech support is worthless even though it's their equipment. Everything worked fine until I went from DSL to fiber, using the same router.
