We use Cloudflare for our DNS and as a firewall.
To cut down on the BS traffic we are getting,
I am considering creating a firewall table on the server (it’s a dedicated server) that allows only cloudflare IP’s and certain specific ones - like ours, paypal, etc.
Naturally, we will still have jackasses that make it pass the cloudflare firewall and come through on cloudflare IP’s, but at least we will stop the ones coming direct to our ‘true’ IP address.
But I wanted to check if there were any known problems or issues with this ‘extra security’ approach?
I Did look around the cloudflare and the community, but didn’t find much about this particular idea.
