<section>
<title>Routing and Proxy ARP</title>
<para>There is one instance where Shorewall creates routing table entries.
When an entry in <filename>/etc/shorewall/proxyarp</filename> contains
"No" in the HAVEROUTE column then Shorewall will create a host route to
the IP address listed in the ADDRESS column through the interface named in
the INTERFACE column. <emphasis role="bold">This is the only case where
Shorewall directly manipulates the routing table</emphasis>.</para>
<para>Example:</para>
<para><filename>/etc/shorewall/proxyarp</filename>:</para>
<programlisting>#ADDRESS INTERFACE EXTERNAL HAVEROUTE PERSISTENT
206.124.146.177 eth1 eth0 No
#LAST LINE -- ADD YOUR ENTRIES BEFORE THIS ONE -- DO NOT REMOVE</programlisting>
<para>The above entry will cause Shorewall to execute the following
command:</para>
<programlisting><emphasis role="bold">ip route add 206.124.146.177 dev eth1</emphasis></programlisting>
