+ <question id="extra-named-port">
+ <para>My named is listening on port 53 and some other
+ high-numbered port? Named is vulnerable a lot, have I
+ been hacked?</para>
+ </question>
+
+ <answer>
+ <para>No. FreeBSD 3.0 and later use a version of named that
+ uses a random high-numbered port for outgoing queries. If
+ you want to use port 53 for outgoing queries, either to
+ get past a firewall or to make yourself feel better, you
+ can use the following in
+ <filename>/etc/namedb/named.conf</filename>
+
+ <programlisting>
+ options {
+ query-source address * port 53;
+ };
+ </programlisting>
+
+ <para>You can replace the * with a single IP address if you
+ want to tighten things further.</para>
+
+ <para>Congratulations, by the way. It's good practice to
+ read your <command>sockstat</command> output and notice
+ odd things.</para>
