Hi Feizhou,
As I'm not at all expert in my understanding of iptables I can't say
definitely that there are any rules on port 53 udp but, here's the
output of /sbin/iptables -L:
[root at sunspot ray]# /sbin/iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere
Chain FORWARD (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain RH-Firewall-1-INPUT (2 references)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT icmp -- anywhere anywhere icmp any
ACCEPT esp -- anywhere anywhere
ACCEPT ah -- anywhere anywhere
ACCEPT udp -- anywhere 224.0.0.251 udp dpt:mdns
ACCEPT udp -- anywhere anywhere udp dpt:ipp
ACCEPT tcp -- anywhere anywhere tcp dpt:ipp
ACCEPT all -- anywhere anywhere state
RELATED,ESTABLISHED
ACCEPT tcp -- anywhere anywhere state NEW
tcp dpt:ssh
REJECT all -- anywhere anywhere reject-with
icmp-host-prohibited

Thanks for all the help and advice!
Kind regards,
