NAME

routestopped - The Shorewall file that governs what traffic flows through the firewall while it is in 'stopped' state.

SYNOPSIS

/etc/shorewall/routestopped

DESCRIPTION

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.

The columns in the file are as follows.

INTERFACE - interface

Interface through which host(s) communicate with the firewall

HOST(S) (Optional) - [-|address[,address]...]

Comma-separated list of IP/subnet addresses. If your kernel and iptables include iprange match support, IP address ranges are also allowed.
If left empty or supplied as "-", 0.0.0.0/0 is assumed.

OPTIONS (Optional) - [-|option[,option]...]

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:
routeback
Set up a rule to ACCEPT traffic from these hosts back to themselves.

source

Allow traffic from these hosts to ANY destination. Without this option or the dest option, only traffic from this host to other listed hosts (and the firewall) is allowed. If source is specified then routeback is redundant.

dest

Allow traffic to these hosts from ANY source. Without this option or the source option, only traffic from this host to other listed hosts (and the firewall) is allowed. If dest is specified then routeback is redundant.

critical

Allow traffic between the firewall and these hosts throughout '[re]start', 'stop' and 'clear'. Specifying critical 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:
•'Ping' nodes with heartbeat.
•LDAP server(s) if you use LDAP Authentication
•NFS Server if you have an NFS-mounted root filesystem.

notrack

The traffic will be exempted from conntection tracking.

PROTO (Optional) - protocol-name-or-number

Only available with Shorewall-perl 4.2.7 and later.

DEST PORT(S) (Optional) - service-name/port-number-list

Only available with Shorewall-perl 4.2.7 and later. A comma-separated list of port numbers and/or service names from /etc/services. May also include port ranges of the form low-port:high-port if your kernel and iptables include port range support.

SOURCE PORT(S) (Optional) - service-name/port-number-list

Only available with Shorewall-perl 4.2.7 and later. A comma-separated list of port numbers and/or service names from /etc/services. May also include port ranges of the form low-port:high-port if your kernel and iptables include port range support.


Note

The source and dest options work best when used in conjunction with ADMINISABSENTMINDED=Yes in shorewall.conf[1](5).

EXAMPLE

Example 1:


         #INTERFACE      HOST(S)                 OPTIONS         PROTO          DEST       SOURCE
         #                                                                      PORT(S)    PORT(S)
         eth2            192.168.1.0/24
         eth0            192.0.2.44
         br0             -                       routeback
         eth3            -                       source
         eth4            -                       notrack        41
