[Samba] Problems DNS access other network hosts

Dear,
The problem is resolvido.Removi the standard rules of CENTOS and dns is
responding.
I do not need these, I have a firewall.
Below is a table with the filter and reject rules CENTOS:


[root at samba ~]# iptables -nvL
Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source
destination
 2527  775K ACCEPT     all  --  *      *       0.0.0.0/0
0.0.0.0/0           state RELATED,ESTABLISHED
    1    60 ACCEPT     icmp --  *      *       0.0.0.0/0
0.0.0.0/0
  889 82153 ACCEPT     all  --  lo     *       0.0.0.0/0

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source
