So am trying to use my router to block Amazon update websites. Trouble is my router only blocks http websites. It does not block https websites.
Further research shows that I may have to set up OPENDNS as my default dns search address. And of course set it with my dynamic address reported to OPENDNS so that everything works. OPENDNS can block Amazon https websites.
Did this years ago. Problem is the first time my dynamic address changes and I do not update on OPENDNS my internet connection will crash.
What a PITA to block Amazon updates on firestick devices.
