I had a similar problem with my Lutron bridge spamming with DHCPv6 requests once a second that I was able to address with a couple of iptables rules to rate-limit the requests before they ever reach dnsmasq. This is what worked for me: ip6tables -I INPUT -p udp -m udp --dport 546:547 -m mac --mac-source 30:45:11:AD:98:6F -j DROP ip6tables -I INPUT -p udp -m udp --dport 546:547 -m mac --mac-source 30:45:11:AD:98:6F -m limit --limit 1/hour -j ACCEPT https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2024q3/017636.html _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk https://lists.thekelleys.org.uk/cgi-bin/mailman/listinfo/dnsmasq-discuss
