What is the issue you’re encountering

Is it possible to block ICMP Timestamp Requests through Cloudflare with rules, or is it automatically done?

What steps have you taken to resolve the issue?

None - this is more of a question of if Cloudflare is a solution. A website my company manages needs to block any ICMP Timestamp Requests, and their host does not do so.

It’s not clear if Cloudflare blocks them, or if it’s possible to set up a firewall rule to block them.

ICMP packets targetting your hostname will be dropped by the Cloudflare edge if the DNS record is proxied since they can’t be forwarded to your origin anyway.

Cloudflare can’t do anything about ICMP requests going to your origin IP address (or using unproxied host names), that you will need to deal with using your firewall.
