How to block an ip range with the firewall

Hello I have tried everyting and also read this forum but I can’t block this ip range using the cloudflare firewall.

The rules is: Ip Address is in 114.119.0.0/16

of course I want to block the range 114.119.x.x

but they are still on my site. I also tried: Country equals singapore and nothing.

It look the only way I can block them is to add the ip one by one.

for example I just blocked: 114.119.129.103 and it works… but there are too many ips from that range.

You can block that range with either an IP access rule or a firewall rule. If they still manage to access your server they will connect most likely directly, around Cloudflare.
