Last year I read many reports and reviews about the plusnet router as I was having stability problems. Many suggested a BT home hub and I have been very pleased with it. Recently I noticed that I could not access my home cctv dvr from the Internet and this had probably been the case since installation. Technically I have successfully set up rules on previous routers and I believe I have done it correctly on thie home hub router. But no apps will view my dvr including the suggested app. I know my DVR ip address and Port 80 is open to it. Using Internet Explorer I can access my DVR and login. Ports 5000 and 8000 are shown as mobile and http ports and both are open to TCP/UDP. All ports have tested as open using an online porting tool. It just appears that any apps that I use (many are similar to set up) will not work. The recommended app used to work on the plusnet router but I don't want to go back to that. All my tests have been done remotely or through the mobile network. Not when I am connected to the same WiFi as the dvr. Am I missing something obvious?
