Suggestions on IP address whitelist

I found that in the docker environment, there is no way to set the IP address whitelist, which causes cloudflare’s cdn may be bypassed. I am concerned that there is an option to set the IP address in Settings>Log>screened_ip_addresses, but I am not sure whether it can be set Default rejection policy

Hope to have the function of IP whitelist

Are you using the Cloudflare template?
