shorewall-routestop(5)
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:o 'Ping' nodes with heartbeat.o LDAP server(s) if you use LDAP Authenticationo NFS Server if you have an NFS-mounted root filesystem. - 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
eth2 192.168.1.0/24
eth0 192.0.2.44
br0 - routeback
eth3 - source
