You should figure out who/what did, then. Those rules don't look like
they were created by Red Hat's tools (where you'd see RH-Firewall...),
and won't be present by default. Something created rules and the rules
don't allow access to TCP or UDP 53 (you need both).
For now, just flush the rules: iptables -F INPUT
