      Do you mean that your server is then only accessible by domain name (if not by IP address)?

      Yes, this does mean it is only accessible by the FQDN.
      You cannot hit a site by the IP of the proxy, Cloudflare in this case. Because the proxy would have no clue what to do with the traffic.

      ML is behind Cloudflare. The IP resolves as 104.26.3.183, among others. If you go to that IP, Cloudflare has no clue WTF to send you to and says so.

      The site I protected as mentioned in the screenshots above is on Vultr and has IP on the Vultr network, obviously. But a lookup only returns the Cloudflare info.

      But even if someone scraped, or the IP was leaked (it is 173.199.114.195), the Vultr Firewall will let nothing connect to that IP except SSH from 2 specific IP addresses and http/https only from the Cloudflare network.

        @JaredBusch OK, but why is access by FQDN safer then access by IP adress?
        And how can Cloudflare distinguish legitimate user from hacker if they both try to access via FQDN?

        (We have one server on Vultr and we access it through IP address. We also have one server on other provider)

          It's not about the FQDN - it's about the fact that from the outside world's point of view, the website lives at CloudFlare... the legit visitors and the hackers only the the IP of CloudFlare, unless there is leakage, as JB mentioned, but even then, the firewall at Vultr prevents the hackers making a connection.

          All legit connections to JB's server in Vultr MUST come through CloudFlare, expect the listed IPs that have access to SSH.

            No one said it is safer. It was only said that it can only be accessed that way.

              But what is the benefit of allowing only through Cloudflare if it is not safer?
              Do you need to subscribe to some service at Cloudflare to use that or not?

                Let me use this example.

                I have a blog on blog.jaredbusch.com (I don't) and it is run using WordPress on Vultr.

                I do the basic and have the traffic going through Cloudflare with the orange cloud.

                Any hacker will hit the site in the legal way through Cloudflare. The Cloudflare network has a lot of defense capabilities built in that you can use depending on your subscription level.

                But assuming you have none of that, it still protects you by not exposing your public IP if nothing else.

                But If I do not restrict access http/https access to the live IP, botnets will quickly discover that IP 10.11.12.13 is running a WP instance. Then the WP hacking bots will attach the system directly via https://10.11.12.13/wp-login.php?WTFEVERHACKWORKSONVERSION etc.

                The Vultr filewall settings as discussed 100% eliminate that possibility.

                  All proxy services can provide protection. It is a matter of what the service provides for what cost and what you want to protect.

                  This thread is not a discussion of the specific uses of Cloudflare. Feel free to make a thread for that.

                    @JaredBusch Thank you.
                    I will read a little about Cloudflare and its services... I am not familiar with that.

                      Even my personal domain, with like no content or traffic was protected from random drive by attacks. For free.

                        Is there any reason not to use at least Cloudflare Free plan and setup Vultr FW to allow only Cloudflare traffic, if we have FQDN for our server?

                          Pretty much never a reason not to do it.

                          I always use Cloudflare already to handle DNS.

                            No reason not to have FQDN for your stuff - it's completely free from CloudFlare.

                              That's not how anything works.

                              You must pay for a domain name.

                              Now you can use all the sub domains you want. But that also gets int other configurations.

                              You do not just have a FQDN.

                                    Yeah - OK, sure, you have to pay for the domain name - but damn.. it's not like that's a fortune or anything...

                                    If you're using a free DynDNS, then the free subs from CF should work as well.

                                      FQDN are never free, there's no way for that. Someone HAS to pay for them, as they cost money. If anyone offered them for free, I'd "buy" every one in existence then sell them to everyone else for way, way more than they cost today.

                                      It's only by having them be $10 a year or whatever that people have to evaluate if they want to pay for them.

                                        But every FQDN from your domain, is free. Whether you have one, or millions.

                                          I was just suprised when @Dashrender said they are free from Cloudflare

                                            I misspoke, I never meant that registered domains themselves were free. What I meant was free was DNS hosting and base level proxying from CF.
