Problem with iptables rules

[fafasino]

Hi everyone,

I'm experiencing slow-downs on certain pages or apps and I wanted to follow the steps mentioned on this page : Why Some Pages Load Slow When Using Pi-hole And How To Fix It (for versions < v4.0) - Pi-hole. But it doesn't work.

Expected Behaviour:

I would like to follow the steps on this tutorial : Why Some Pages Load Slow When Using Pi-hole And How To Fix It (for versions < v4.0) - Pi-hole, but I'm having trouble with the iptables rules. iptables -A INPUT -p tcp --destination-port 443 -j REJECT --reject-with tcp-reset.

Actual Behaviour:

Pi hole is not recognising the command destination port (iptables v1.8.2 (nf_tables): unknown option "--destination-port").

But it doesn't work.

That post is almost three years old and “ for versions < v4.0”.
