Yes, I have this in place now, but I try to let the fw drop them:
This seems not working:
udp_inbound_dns_options = 'keep state (max-src-conn-rate 120/60, overload
<bruteforce> flush global )'
…
pass in quick on $red_if proto udp from any to { $ns4, $ns5 } \
port { domain } tag RED_DMZ $udp_inbound_dns_options label "dns inbound"
Is this not possible with udp?
