Does the count field from "iptables -vnL RH-Firewall-1-INPUT" show
your REJECT rules being hit?
Yes, the rule gets hit and it returns an answer to the DNS query
anyway. I saw it increment from 10 to 11 when I ran the query:
11 692 REJECT udp -- * * 10.100.1.1
0.0.0.0/0 udp dpt:53 reject-with icmp-port-unreachable
I seriously doubt that the response came from this machine since
the packet that hit that rule died right there. Does the machine
that sent the request have a secondary DNS server configured?
The REJECT response would have resulted in an immediate query to
the next server.
