Is CloudFlare compatible with Bad Behavior?

Absolutely. Please make sure you're working on the latest version of Bad Behavior to ensure best performance. You would also want to enable the following in Bad Behavior:

**Reverse Proxy**
Turned on

**Reverse Proxy Header**
Change the default of “X-Forwarded-For” to “CF-Connecting-IP”

Note: You don't need to whitelist CloudFlare's IPs because the CF-Connecting-IP" will restore this.
