<P>The <CODE>acl</CODE> statement creates a named address match list.
It gets its name from a primary use of address match lists:  Access

<CODE>acl</CODE> before it can be used elsewhere; no forward
references are allowed.</P>

<DD>
Allows all hosts.

<DT><CODE>none</CODE>
<DD>

<DT><CODE>localhost</CODE>
<DD>
Allows the IP addresses of all interfaces on the system.

<DT><CODE>localnets</CODE>
