<para>specify multiple private subnets behind the left participant, expressed as
{
<emphasis remap='I'>networkA</emphasis><emphasis remap='B'>/</emphasis><emphasis remap='I'>netmaskA</emphasis> 
<emphasis remap='I'>networkB</emphasis><emphasis remap='B'>/</emphasis><emphasis remap='I'>netmaskB</emphasis>

}
If both a leftsubnets= and rightsubnets= is defined, all combinations of
subnet tunnels will be instantiated. You cannot use leftsubnet and leftsubnets together. For examples see <emphasis remap='I'>testing/pluto/multinet-*</emphasis>.
