Externally I use Cloudflare proxy and internally I put Crowdsec and Modsecurity CRS middlewares in front of Traefik.
After some fine-tuning and eliminating false positives, it is running smoothly. It logs all the temporarily banned and reported IPs (to Crowdsec) and logging them to a Discord channel. On average it blocks a few dozen different IPs each day.
From what I see, there are far more American IPs trying to access non-public resources and attempting to exploit CVEs than there are Chinese ones.
I don't really mind anyone scraping publicly accessible content and the rest is either gated by SSO or located in intranet.
For me personally there is no need to block a specific country, I think that trying to block exploit or flooding attempts is a better approach.
