.SH "Description"
.PP
The blacklist file is used to perform static blacklisting\&. You can blacklist by source address (IP or MAC), or by application\&.
.PP
The columns in the file are as follows\&.
.PP
\fBADDRESS/SUBNET\fR \- {\fB\-\fR|\fB~\fR\fImac\-address\fR|\fIip\-address\fR|\fIaddress\-range\fR|\fB+\fR\fIipset\fR}
.RS 4
Host address, network address, MAC address, IP address range (if your kernel and iptables contain iprange match support) or ipset name prefaced by "+" (if your kernel supports ipset match)\&.
.sp
MAC addresses must be prefixed with "~" and use "\-" as a separator\&.
.sp
Example: ~00\-A0\-C9\-15\-39\-78
.sp
A dash ("\-") in this column means that any source address will match\&. This is useful if you want to blacklist a particular application using entries in the PROTOCOL and PORTS columns\&.
.RE
.PP
\fBPROTOCOL\fR (Optional) \- {\fB\-\fR|[!]\fIprotocol\-number\fR|[!]\fIprotocol\-name\fR}
.RS 4
If specified, must be a protocol number or a protocol name from protocols(5)\&.
.RE
.PP
\fBPORTS\fR (Optional) \- {\fB\-\fR|[!]\fIport\-name\-or\-number\fR[,\fIport\-name\-or\-number\fR]\&.\&.\&.}
.RS 4
May only be specified if the protocol is TCP (6) or UDP (17)\&. A comma\-separated list of destination port numbers or service names from services(5)\&.
.RE
.PP
When a packet arrives on an interface that has the
\fBblacklist\fR
option specified in
\m[blue]\fBshorewall\-interfaces\fR\m[]\&\s-2\u[1]\d\s+2(5), its source IP address and MAC address is checked against this file and disposed of according to the
\fBBLACKLIST_DISPOSITION\fR
and
\fBBLACKLIST_LOGLEVEL\fR
variables in
\m[blue]\fBshorewall\&.conf\fR\m[]\&\s-2\u[2]\d\s+2(5)\&. If
\fBPROTOCOL\fR
or
\fBPROTOCOL\fR
and
\fBPORTS\fR
are supplied, only packets matching the protocol (and one of the ports if
\fBPORTS\fR
supplied) are blocked\&.
.SH "Example"
