  • How do we block an entire ISP?

    We are getting massive amounts of hits from these two ISP's Hudson Valley Host and ColoCrossing. How can we block the entire ISP?

    Thank you!

        We installed cloudflare last night and it looks great, but these bot ips are still coming thru. Do you think if we move to another server it would help? We have uploaded 1,200 ips and that still is not stopping them.

        UPDATE: We contacted Cloudflare about this and they told us to get the ASN number for the isp and that blocked the entire range. Thank you for this information and it a huge help for us.

        Thank you again - Damien

          Does cloudflare have access to the customer's credit card information? It seems that the 3D site feeds to them. Does the checkout feed to them?

            No, they do not have access to that information. This has been a lifesaver for us. I think we have been getting hacked since last November, I don't know why we didn't do this sooner. You should get it today.

              If cloudflare is letting the traffic through, there's a very good chance that the traffic is OK to let through.

              I wouldn't block anything cloudlfare doesn't block already. Their service "learns" traffic patterns from their other clients, and when it sees attacks, it blocks them automatically.

              Blocking entire ISP's, Countries, or even single IP's is simply not a good thing to do. When cloudflare blocks an IP, it has a really high confidence level that this particular IP is actively engaging in malicious activity at this moment in time. Cloudflare then automatically un-blocks the IP after some time has passed.

              I would recommend you remove all of your 3dCart IP blocks that you put in place prior to using Cloudflare as well.

              Cloudlfare also acts like a CDN of sorts, so they will improve your site performance as well as reduce how much bandwidth you consume from your 3dcart server. For us, it's about half of our bandwidth usage is saved by cloudflare's caching (mostly images).

              @PackSecure - Cloudflare sits in front of your website. You move DNS over to them, and follow their easy guide to get going. Essentially then, all traffic going to your site ends up going through Cloudflare. Cloudflare will serve images, css, javascript, and your other static assets directly from their servers. The only thing that goes back to your server is for the HTML itself, or if cloudlfare doens't have some resource already cached. Cloudflare has servers all around the world, so your customers will be served by the closest server to them, which improves performance even further.

              Just a tip, we found that the caching on certain pages caused some issues for us. We used the Page Rules to tell cloudflare not to cache content on the checkout pages, my account pages, and view cart pages. We also told them not to cache anything from the /admin/* directories. Works well for us.
