Ban traffic from X unless OS is Y

[danielrosehill]

Hi guys,

Was wondering if anybody would be able to advise whether this is possible.

I’d like to create a firewall rule in Cloudflare panning traffic from IPs in country X unless their OS is Y (Linux).

Can such a rule be created?

Thank you!

Something like that should work.

Of course that is based on the user agent, which can be easily forged, but then, welcome to the Internet
