.SH "Name"
routestopped \- The Shorewall file that governs what traffic flows through the firewall while it is in \'stopped\' state\&.
.SH "Synopsis"

\fB/etc/shorewall/routestopped\fR
.fam
.SH "Description"
.PP
This file is used to define the hosts that are accessible when the firewall is stopped or is being stopped\&. When shorewall\-shell is being used, the file also determines those hosts that are accessible when the firewall is in the process of being [re]started\&.
.PP
The columns in the file are as follows\&.
.PP
\fBINTERFACE\fR \- \fIinterface\fR
.RS 4
Interface through which host(s) communicate with the firewall
.RE
.PP
\fBHOST(S)\fR (Optional) \- [\fB\-\fR|\fIaddress\fR[,\fIaddress\fR]\&.\&.\&.]
.RS 4
Comma\-separated list of IP/subnet addresses\&. If your kernel and iptables include iprange match support, IP address ranges are also allowed\&.
.sp
If left empty or supplied as "\-", 0\&.0\&.0\&.0/0 is assumed\&.
.RE
.PP
\fBOPTIONS\fR (Optional) \- [\fB\-\fR|\fIoption\fR[\fB,\fR\fIoption\fR]\&.\&.\&.]
.RS 4
A comma\-separated list of options\&. The order of the options is not important but the list can contain no embedded whitespace\&. The currently\-supported options are:
.PP
\fBrouteback\fR
.RS 4
Set up a rule to ACCEPT traffic from these hosts back to themselves\&.
.RE
.PP
\fBsource\fR
.RS 4
Allow traffic from these hosts to ANY destination\&. Without this option or the
\fBdest\fR
option, only traffic from this host to other listed hosts (and the firewall) is allowed\&. If
\fBsource\fR
is specified then
\fBrouteback\fR
is redundant\&.
.RE
.PP
\fBdest\fR
.RS 4
Allow traffic to these hosts from ANY source\&. Without this option or the
\fBsource\fR
option, only traffic from this host to other listed hosts (and the firewall) is allowed\&. If
\fBdest\fR
is specified then
\fBrouteback\fR
is redundant\&.
.RE
.PP
\fBcritical\fR
.RS 4
Allow traffic between the firewall and these hosts throughout \'[re]start\', \'stop\' and \'clear\'\&. Specifying
\fBcritical\fR
on one or more entries will cause your firewall to be "totally open" for a brief window during each of those operations\&. Examples of where you might want to use this are:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
\'Ping\' nodes with heartbeat\&.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
LDAP server(s) if you use LDAP Authentication
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.sp -1
.IP \(bu 2.3
.\}
NFS Server if you have an NFS\-mounted root filesystem\&.
.RE
.RE
.PP
notrack
.RS 4
The traffic will be exempted from conntection tracking\&.
.RE
.RE
.PP
PROTO (Optional) \(en \fIprotocol\-name\-or\-number\fR
.RS 4
Only available with Shorewall\-perl 4\&.2\&.7 and later\&.
.RE
.PP
DEST PORT(S) (Optional) \(en \fIservice\-name/port\-number\-list\fR
.RS 4
Only available with Shorewall\-perl 4\&.2\&.7 and later\&. A comma\-separated list of port numbers and/or service names from
\FC/etc/services\F[]\&. May also include port ranges of the form
\fIlow\-port\fR:\fIhigh\-port\fR
if your kernel and iptables include port range support\&.
.RE
.PP
SOURCE PORT(S) (Optional) \(en \fIservice\-name/port\-number\-list\fR
.RS 4
Only available with Shorewall\-perl 4\&.2\&.7 and later\&. A comma\-separated list of port numbers and/or service names from
\FC/etc/services\F[]\&. May also include port ranges of the form
\fIlow\-port\fR:\fIhigh\-port\fR
if your kernel and iptables include port range support\&.
