I have a DrayTek Vigor 2860ac dual-band router and I have put the three rules into the firewall according to the instructions in another thread, the first two to send all dns requests to OpenDNS and the last to block all other dns requests. However, if I enable the third (blocking) rule, some devices on my network can't connect to the router. My daughter's laptop and mobile phone work just fine, as does my Panasonic Bluray recorder and Epson printer, but my Amazon FireTV won't connect and neither will my PC or my son's PC. I've checked that I have input the settings exactly as shown in the screenshots and I can't find any errors. It seems strange that some devices will connect OK, while others won't connect at all. If I disable the third rule, everything connects just fine. Has anyone any idea what might be the problem?
