+    <variablelist>
+      <varlistentry>
+        <term>Host Address</term>
+
+        <listitem>

+
+          <para>In IPv4, the format is <emphasis>i.j.k.l</emphasis> where
+          <emphasis>i</emphasis> through <emphasis>l</emphasis> are decimal
+          numbers between 1 and 255.</para>
+
+          <para>In IPv6, the format is <emphasis>a:b:c:d:e:f:g:h</emphasis>
+          where <emphasis>a</emphasis> through <emphasis>h</emphasis> consist
+          of 1 to 4 hexidecimal digits (leading zeros may be omitted). a
+          single series of 0 addresses may be omitted. For example
+          2001:227:e857:1:0:0:0:0:1 may be written 2001:227:e857:1::1.</para>
+        </listitem>
+      </varlistentry>
+
+      <varlistentry>
+        <term>Network Address</term>
+
+        <listitem>
+          <para>A network address refers to 1 or more hosts and consists of a
+          host address followed by a slash ("/") and a <firstterm>Variable
+          Length Subnet Mask</firstterm> (VLSM). This is known as
+          <firstterm>Classless Internet Domain Routing</firstterm> (CIDR)
+          notation.</para>
+
+          <para>The VLSM is a decimal number. For IPv4, it is in the range 0
+          through 32. For IPv6, the range is 0 through 128. The number
+          represents the number of leading bits in the address that represent
+          the network address; the remainder of the bits are a host address
+          and are generally given as zero.</para>
+
+          <para>Examples:</para>
+
+          <para>IPv4: 192.168.1.0/24</para>
+
+          <para>IPv6: 2001:227:e857:1:0:0:0:0:1/64</para>
+        </listitem>
+      </varlistentry>
+    </variablelist>
+
+    <para>In the Shorewall documentation and manpages, we have tried to make
+    it clear which type of address is accepted in each specific case.</para>
+
+    <para>Because Shorewall uses a colon (":") as a separator in many
+    contexts, IPv6 addresses are best written using the standard convention in
+    which the address itself is enclosed in square brackets:</para>
+
+    <simplelist>
+      <member>[2001:227:e857:1::1]</member>

+    <title>Specifying SOURCE and DEST</title>
+
+    <para>Entries in Shorewall configuration files often deal with the source
+    (SOURCE) and destination (DEST) of connections and Shorewall implements a
+    uniform way for specifying them.</para>
+
+    <para>A SOURCE or DEST consists of one to three parts separated by colons

+    <title>Alternative Specification of Column Values</title>
+
+    <para>Some of the configuration files now have a large number of columns.
+    That makes it awkward to specify a value for one of the right-most columns
+    as you must have the correct number of intervening '-' columns.</para>
+
+    <para>This problem is addressed by allowing column values to be specified
+    as <replaceable>column-name</replaceable>/<replaceable>value</replaceable>
+    pairs.</para>
+
+    <para>There is considerable flexibility in how you specify the
+    pairs:</para>
+
+    <itemizedlist>
+      <listitem>
+        <para>At any point, you can enter a left curly bracket ('{') followed
+        by one or more specifications of the following forms:</para>
+
+        <simplelist>
+          <member><replaceable>column-name</replaceable>=<replaceable>value</replaceable></member>
+
+          <member><replaceable>column-name</replaceable>=<replaceable>&gt;value</replaceable></member>
+
+          <member><replaceable>column-name</replaceable>:<replaceable>value</replaceable></member>
+        </simplelist>
+
+        <para>The pairs must be followed by a right curly bracket
+        ("}").</para>
+
+        <para>The value may optionally be enclosed in double quotes.</para>
+
+        <para>The pairs must be separated by white space, but you can add a
+        comma adjacent to the <replaceable>values</replaceable> for
+        readability as in:</para>
+
+        <simplelist>
+          <member><emphasis role="bold">{ proto=&gt;udp, port=1024
+          }</emphasis></member>
+        </simplelist>
+      </listitem>
+
+      <listitem>
+        <para>You can also separate the pairs from columns by using a
+        semicolon:</para>
+
+        <simplelist>
+          <member><emphasis role="bold">; proto:udp,
+          port:1024</emphasis></member>
+        </simplelist>
+      </listitem>
+    </itemizedlist>
+
+    <para>In Shorewall 5.0.3, the sample configuration files and the man pages
+    were updated to use the same column names in both the column headings and
+    in the alternate specification format. The following table shows the
+    column names for each of the table-oriented configuration files.</para>

+
+    <para>When you define an object in Shorewall (<ulink
+    url="manpages/shorewall-zones.html">Zone</ulink>, <link
+    linkend="Logical">Logical Interface</link>, <ulink
+    url="ipsets.html">ipsets</ulink>, <ulink
+    url="Actions.html">Actions</ulink>, etc., you give it a name. Shorewall
+    names start with a letter and consist of letters, digits or underscores
+    ("_"). Except for Zone names, Shorewall does not impose a limit on name
+    length.</para>
+
+    <para>When an ipset is referenced, the name must be preceded by a plus
+    sign ("+").</para>
+
+    <para>The last character of an interface may also be a plus sign to
+    indicate a wildcard name.</para>
+
+    <para>Physical interface names match names shown by 'ip link ls'; if the
+    name includes an at sign ("@"), do not include that character or any
+    character that follows. For example, "sit1@NONE" is referred to as simply
+    'sit1".</para>

+
+  <refsect1>
+    <title>Zone and Chain Names</title>
+
+    <para>For a pair of zones, Shorewall creates two Netfilter chains; one for
+    connections in each direction. The names of these chains are formed by
+    separating the names of the two zones by either "2" or "-".</para>
+
+    <para>Example: Traffic from zone A to zone B would go through chain A2B
+    (think "A to B") or "A-B".</para>
+
+    <para>In Shorewall 4.6, the default separator is "-" but you can override
+    that by setting ZONE_SEPARATOR="2" in <ulink
+    url="manpages/shorewall.conf.html">shorewall.conf</ulink> (5).</para>
+
+    <note>
+      <para>Prior to Shorewall 4.6, the default separator was "2".</para>
+    </note>
+
+    <para>Zones themselves have names that begin with a letter and are
+    composed of letters, numerals, and "_". The maximum length of a name is
+    dependent on the setting of LOGFORMAT in <ulink
+    url="manpages/shorewall.conf.html">shorewall.conf</ulink> (5). See <ulink
+    url="manpages/shorewall-zones.html">shorewall-zones</ulink> (5) for

+    <title>Using DNS Names</title>
+
+    <caution>
+      <para>I personally recommend strongly against using DNS names in
+      Shorewall configuration files. If you use DNS names and you are called
+      out of bed at 2:00AM because Shorewall won't start as a result of DNS
+      problems then don't say that you were not forewarned.</para>
+    </caution>
+
+    <para>Host addresses in Shorewall configuration files may be specified as
+    either IP addresses or DNS Names.</para>
+
+    <para>DNS names in iptables rules aren't nearly as useful as they first
+    appear. When a DNS name appears in a rule, the iptables utility resolves
+    the name to one or more IP addresses and inserts those addresses into the
+    rule. So changes in the DNS-&gt;IP address relationship that occur after
+    the firewall has started have absolutely no effect on the firewall's rule
+    set.</para>
+
+    <para>For some sites, using DNS names is very risky. Here's an
+    example:</para>
+
+    <programlisting>teastep@ursa:~$ dig pop.gmail.com
+

+
+    <para>Note that the TTL is 300 -- 300 seconds is only 5 minutes. So five
+    minutes later, the answer may change!</para>
+
+    <para>So this rule may work for five minutes then suddently stop
+    working:</para>
+
+    <programlisting>#ACTION        SOURCE               DEST              PROTO             DPORT

+
+    <para>There are two options in <ulink
+    url="manpages/shorewall.conf.html">shorewall[6].conf(5)</ulink> that
+    affect the use of DNS names in Shorewall[6] config files:</para>
+
+    <itemizedlist>
+      <listitem>
+        <para>DEFER_DNS_RESOLUTION - When set to No, DNS names are resolved at
+        compile time; when set to Yes, DNS Names are resolved at
+        runtime.</para>
+      </listitem>
+
+      <listitem>
+        <para>AUTOMAKE - When set to Yes, <command>start</command>,

+        in compilation if one of the files on the CONFIG_PATH has changed
+        since the the last compilation.</para>
+      </listitem>
+    </itemizedlist>
+
+    <para>So by setting AUTOMAKE=Yes, and DEFER_DNS_RESOLUTION=No, compilation
+    will only take place at boot time if a change had been make to the config
+    but no <command>restart</command> or <command>reload</command> had taken
+    place. This is clearly spelled out in the shorewall.conf manpage. So with
+    these settings, so long as a 'reload' or 'restart' takes place after the
+    Shorewall configuration is changes, there should be no DNS-related
+    problems at boot time.</para>
+
+    <important>
+      <para>When DEFER_DNS_RESOLUTION=No and AUTOMAKE=Yes and a DNS change
+      makes it necessary to recompile an existing firewall script, the

+      recompilation.</para>
