Firewall install

Dear sir,

  1. If I have a website and want to use Cloudflare to protect, do I need to install clouflare on my server?
  2. If I have a domain name and I want to use Cloudflare to protect, do I need to change the DNS ?
    3 I cannot see the difference between free, 20$/mon and 200$/mon plan? only response time?

A post was merged into an existing topic: Installation for Cloudflare

Moved my response to your other post. Please don’t double-post.
