How to solve the problem of source IP leakage and DD attacks even when using Cloudflare CDN?

but in my case with ufw, it’s worth mentioning docker bypasses ufw by default so you need to make sure to apply the rules to your internal docker ip’s as well.

You will want to use the firewall that your VPS provider provides for you. Using a host based firewall will be far less effective in fighting a DDoS since the traffic does get to your network stack.
