<para>SOURCE - The source of the packet. If the packet originates on
the firewall, place <quote>$FW</quote> in this column. Otherwise,
this is a comma-separated list of interface names, IP addresses, MAC
addresses in Shorewall Format and/or Subnets.</para>
<para>SOURCE - Source of the packet. A comma-separated list of
interface names, IP addresses, MAC addresses and/or subnets for
packets being routed through a common path. List elements may also
consist of an interface name followed by ":" and an address (e.g.,
eth1:192.168.1.0/24). For example, all packets for connections
masqueraded to eth0 from other interfaces can be matched in a single
rule with several alternative SOURCE criteria. However, a connection
whose packets gets to eth0 in a different way, e.g., direct from the
firewall itself, needs a different rule.</para>
<para>Examples <programlisting> eth0 192.168.2.4,192.168.1.0/24</programlisting></para>
<para>Accordingly, use $FW in its own separate rule for packets
originating on the firewall. In such a rule, the MARK column may NOT
specify either ":P" or ":F" because marking for firewall-originated
packets always occurs in the OUTPUT chain.</para>
<para>MAC addresses must be prefixed with "~" and use "-" as a
separator.</para>
<para>Example: ~00-A0-C9-15-39-78</para>

<para>DEST - Destination of the packet. Comma-separated list of IP

<para>DEST - Destination of the packet. Comma separated list of IP
addresses and/or subnets. If your kernel and iptables include
iprange match support, IP address ranges are also allowed. List
elements may also consist of an interface name followed by ":" and
an address (e.g., eth1:192.168.1.0/24). If the MARK column
specificies a classification of the form &lt;major&gt;:&lt;minor&gt;
then this column may also contain an interface name.</para>

<para>PROTO - Protocol - Must be the name of a protocol from
/etc/protocol, a number or <quote>all</quote></para>
<para>PROTO - Protocol - Must be "tcp", "udp", "icmp", "ipp2p",
"ipp2p:udp", "ipp2p:all" a number, or "all". "ipp2p" requires ipp2p
match support in your kernel and iptables. </para>
</listitem>
<listitem>
<para>PORT(S) - Destination Ports. A comma-separated list of Port
names (from /etc/services), port numbers or port ranges (e.g.,
21:22); if the protocol is <quote>icmp</quote>, this column is
interpreted as the destination icmp type(s).</para>
names (from /etc/services), port numbers or port ranges; if the
protocol is "icmp", this column is interpreted as the destination
icmp-type(s).</para>
<para>If the protocol is ipp2p, this column is interpreted as an
ipp2p option without the leading "--" (example "bit" for
bit-torrent). If no PORT is given, "ipp2p" is assumed.</para>
<para>This column is ignored if PROTOCOL = all but must be entered
if any of the following field is supplied. In that case, it is
suggested that this field contain "-"</para>
