My mom keeps typing in wrong URLs with typos and getting sent to Chinese typosquatting malware or fraud sites, so I want to configure my home router to block all traffic to and from China as much as possible.
Did some research on this and none of the search results are conclusive. It's possible the instructions vary by router.
The solution doesn't have to be 100%. In fact, some of the search results I found hinted that perfect geographic blocking is impossible because the blocking tables would be too large. For my purposes, blocking >= 95% of China should be sufficient protection.
Due diligence searching: I see a lot of questions and no really good answers.
Most jarring is the complete absence of specific step-by-step instructions on how to configure this for beginners who have no clue where to start. That's what I'm looking for: "How to configure geographic web traffic blocking on a home router for dummies".
Something else that further makes the search difficult is that most of the questions are framed in the context of web site operators who want to block geographic regions known to cause trouble on the Web (usually Russia, China, and sometimes parts of Eastern Europe). I'm looking for the reverse - block all websites and traffic to/from known generally malicious regions.
If the instructions are specific to each router, post a comment and I'll reply with the type of my router.
Another alternative is setting up a firewall program on her computer set up to block China and other known bad-actor countries as needed.
