<listitem>
<para>If there is already a route from the firewall to the host
whose address is given, enter <emphasis role="bold">Yes</emphasis>
or <emphasis role="bold">yes</emphasis> in this column. Otherwise,
enter <emphasis role="bold">no</emphasis> or <emphasis
role="bold">No</emphasis> or leave the column empty and Shorewall
will add the route for you. If Shorewall adds the route,the route
will be persistent if the <emphasis
role="bold">PERSISTENT</emphasis> column contains <emphasis
role="bold">Yes</emphasis>; otherwise, <emphasis
role="bold">shorewall stop</emphasis> or <emphasis

<emphasis role="bold">no</emphasis>, then the value of this column
determines if the route added by Shorewall persists after a
<emphasis role="bold">shorewall stop</emphasis> or a <emphasis
role="bold">shorewall clear</emphasis>. If this column contains
<emphasis role="bold">Yes</emphasis> or <emphasis
role="bold">yes</emphasis> then the route persists; If the column is
empty or contains <emphasis role="bold">No</emphasis> or <emphasis
role="bold">no</emphasis> then the route is deleted at

<para> Entries in this file cause traffic to be routed to one of the
providers listed in shorewall-providers(5).</para>
<para>The columns in the file are as follows.</para>
<variablelist>
<varlistentry>
<term><emphasis role="bold">SOURCE</emphasis> (Optional)</term>
<listitem>
<para>An ip address (network or host) that matches the source IP
address in a packet. May also be specified as an interface name
optionally followed by ":" and an address. If the device <emphasis
role="bold">lo</emphasis> is specified, the packet must originate
from the firewall itself.</para>
</listitem>
</varlistentry>
<varlistentry>
<term> <emphasis role="bold">DEST</emphasis> (Optional)</term>
<listitem>
<para>An ip address (network or host) that matches the destination
IP address in a packet.</para>
<para>If you choose to omit either <emphasis
role="bold">SOURCE</emphasis> or <emphasis
role="bold">DEST</emphasis>, place "-" in that column. Note that you
may not omit both <emphasis role="bold">SOURCE</emphasis> and
<emphasis role="bold">DEST</emphasis>.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">PROVIDER</emphasis></term>
<listitem>
<para>The provider to route the traffic through. May be expressed
either as the provider name or the provider number. May also be
<emphasis role="bold">main</emphasis> or 254 for the main routing
table. This can be used in combination with VPN tunnels, see example
2 below.</para>
</listitem>
</varlistentry>
<varlistentry>
<term><emphasis role="bold">PRIORITY</emphasis></term>
<listitem>
<para> The rule's priority which determines the order in which the
rules are processed.</para>
<variablelist>
<varlistentry>
<term>1000-1999</term>
<listitem>
<para>Before Shorewall-generated 'MARK' rules</para>
</listitem>

<para>After 'MARK' rules but before Shorewall-generated rules
for ISP interfaces.</para>

<listitem>
<para>After ISP interface rules but before 'default'
rule.</para>

ISP1 provider.</para>

eth1 - ISP1 1000

</varlistentry>
<varlistentry>
<term>Example 2:</term>
<listitem>
<para>You use OpenVPN (routed setup /tunX) in combination with
multiple providers. In this case you have to set up a rule to ensure
that the OpenVPN traffic is routed back through the tunX
interface(s) rather than through any of the providers. 10.8.0.0/24
is the subnet choosen in your OpenVPN configuration (server 10.8.0.0
255.255.255.0).</para>
