Hello, My router is crap, while it says it can block domains, it is not really blocking them. It is just blocking TCP connections on ports 80 (and maybe 443). If you try to navigate to a blocked domain you will be redirected to a local webpage stating that site is blocked.However, you can still reach those destinations with ICMP, for example. My questions is would that be enough protection against unwanted updates or should I use another method? Thank you.
