-	</question>
-
-	<answer>
-	  <para>BIND uses a random high-numbered port for outgoing
-	    queries.  Recent versions of it choose a new, random UDP
-	    port for each query.  This may cause problems for some
-	    network configurations, especially if a firewall blocks
-	    incoming UDP packets on particular ports.  To
-	    get past that firewall, try the
-	    <literal>avoid-v4-udp-ports</literal> and
-	    <literal>avoid-v6-udp-ports</literal> options to avoid
-	    selecting random port numbers within a blocked
-	    range.</para>
-
-	  <warning>
-	    <para>If a port number (like 53) is specified via the
-	      <literal>query-source</literal> or
-	      <literal>query-source-v6</literal> options in
-	      <filename>/usr/local/etc/namedb/named.conf</filename>,
-	      randomized
-	      port selection will not be used.  It is strongly
-	      recommended that these options not be used to specify
-	      fixed port numbers.</para>
