Name

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

Warning

Changes to this file do not take effect until after the next shorewall start or shorewall restart command.

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. Beginning with Shorewall 4.4.9, this option is automatically set if routeback is specified in shorewall-interfaces (5) or if the rules compiler detects that the interface is a bridge.

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.

notrack

The traffic will be exempted from conntection tracking.

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

Protocol.

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

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

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(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
