22d5d84393d960a2027f472036f3fee15d7dbce9nd <p>The first argument to this directive is always
22d5d84393d960a2027f472036f3fee15d7dbce9nd <code>from</code>. The subsequent arguments can take three
22d5d84393d960a2027f472036f3fee15d7dbce9nd different forms. If <code>Allow from all</code> is specified, then
22d5d84393d960a2027f472036f3fee15d7dbce9nd all hosts are allowed access, subject to the configuration of the

22d5d84393d960a2027f472036f3fee15d7dbce9nd that it matches the original IP address. Only if the forward
