Unfortunately on the morning of the 19th June our board was attacked by a range of IP's originating from Chinese locations (DDoS).
The site was disabled by the ISP to prevent further damage.
Before I bring the board back up I am looking to implement the following;
1) Block significant ranges of IP addresses originating from China.
2) Introduce Cloudflare, and install the Cloudflare extension for IP.
3) Introduce first only posts to guests - https://www.phpbb.com/customise/db/exte ... _to_guest/
(I'm not sure, but I couldn't see an option to allow bots past this so they can still index. Will this stop indexing?).
I am hoping this combination will prevent attacks of this nature in future.
Any thoughts or opinions on this approach would be gratefully received?
