6 routestopped - The Shorewall file that governs what traffic flows
7 through the firewall while it is in 'stopped' state.
8
10 /etc/shorewall/routestopped
11
13 This file is used to define the hosts that are accessible when the
14 firewall is stopped or is being stopped. When shorewall-shell is being
15 used, the file also determines those hosts that are accessible when the
16 firewall is in the process of being [re]started.
17
18 The columns in the file are as follows.
19
20 INTERFACE — interface
21 Interface through which host(s) communicate with the firewall
22
23 HOST(S) (Optional) — [-|address[,address]...]
24 Comma-separated list of IP/subnet addresses. If your kernel and
25 iptables include iprange match support, IP address ranges are
26 also allowed.
27
28 If left empty or supplied as "-", 0.0.0.0/0 is assumed.
29
30 OPTIONS (Optional) — [-|option[,option]...]
31 A comma-separated list of options. The order of the options is
32 not important but the list can contain no embedded whitespace.
33 The currently-supported options are:
34
35 routeback
36 Set up a rule to ACCEPT traffic from these hosts back to
37 themselves.
38
39 source Allow traffic from these hosts to ANY destination. With‐
40 out this option or the dest option, only traffic from
41 this host to other listed hosts (and the firewall) is al‐
42 lowed. If source is specified then routeback is redun‐
43 dant.
44
45 dest Allow traffic to these hosts from ANY source. Without
46 this option or the source option, only traffic from this
47 host to other listed hosts (and the firewall) is allowed.
48 If dest is specified then routeback is redundant.
49
50 critical
51 Allow traffic between the firewall and these hosts
52 throughout '[re]start', 'stop' and 'clear'. Specifying
53 critical on one or more entries will cause your firewall
54 to be "totally open" for a brief window during each of
55 those operations. Examples of where you might want to use
56 this are:
57
58 · 'Ping' nodes with heartbeat.
59
60 · LDAP server(s) if you use LDAP Authentication
61
62 · NFS Server if you have an NFS-mounted root filesystem.
63 Note
64
65 The source and dest options work best when used in conjunction
66 with ADMINISABSENTMINDED=Yes in shorewall.conf
67 ⟨shorewall.conf.html⟩ (5).

70 Example 1:
71 #INTERFACE HOST(S) OPTIONS
72 eth2 192.168.1.0/24
73 eth0 192.0.2.44
74 br0 - routeback
75 eth3 - source
