blrules - shorewall6 Blacklist file
This file is used to perform zone-specific blacklisting and
Rules in this file are applied depending on the setting of
BLACKLISTNEWONLY in shorewall6.conf(5). If BLACKLISTNEWONLY=No, then
they are applied regardless of the connection tracking state of the
packet. If BLACKLISTNEWONLY=Yes, they are applied to connections in the
NEW and INVALID states.
The format of rules in this file is the same as the format of rules in
shorewall6-rules (5). The differece in the two files lies in the
ACTION (first) column.
Specifies the action to be taken if the packet matches the rule.
Must be one of the following.
May only be used if BLACKLIST_LOGLEVEL is specified in
shorewall6.conf(5). Logs, audits (if specified) and applies
the BLACKLIST_DISPOSITION specified in shorewall6.conf (5).
Exempt the packet from the remaining rules in this file.
Ignore the packet.
A_DROP and A_DROP!
Audited versions of DROP. Requires AUDIT_TARGET support in the
kernel and ip6tables.
disallow the packet and return an icmp-unreachable or an RST
Audited versions of REJECT. Require AUDIT_TARGET support in the
kernel and ip6tables.
Simply log the packet and continue with the next rule.
Queue the packet to a user-space application such as ftwall
(http://p2pwall.sf.net). The application may reinsert the
packet for further processing.
queues matching packets to a backend logging daemon via a
netlink socket then continues to the next rule. See
Queues the packet to a user-space application using the
nfnetlink_queue mechanism. If a queuenumber is not specified,
queue zero (0) is assumed.
the rest of the line will be attached as a comment to the
Netfilter rule(s) generated by the following entries. The
comment will appear delimited by "/* ... */" in the output of
"shorewall6 show <chain>". To stop the comment from being
attached to further rules, simply include COMMENT on a line by
The name of an action declared in shorewall6-actions(5) or
The name of a macro defined in a file named macro.macro. If the
macro accepts an action parameter (Look at the macro source to
see if it has PARAM in the TARGET column) then the macro name
is followed by the parenthesized target (ACCEPT, DROP, REJECT,
...) to be substituted for the parameter.
The ACTION may optionally be followed by ":" and a syslog log level
(e.g, REJECT:info or Web(ACCEPT):debug). This causes the packet to
be logged at the specified level.
If the ACTION names an action declared in shorewall6-actions(5)
or in /usr/share/shorewall6/actions.std then:
o If the log level is followed by "!' then all rules in the
action are logged at the log level.
o If the log level is not followed by "!" then only those rules
in the action that do not specify logging are logged at the
o The special log level none! suppresses logging by the action.
You may also specify NFLOG (must be in upper case) as a log
level.This will log to the NFLOG target for routing to a separate
log through use of ulogd
Actions specifying logging may be followed by a log tag (a string
of alphanumeric characters) which is appended to the string
generated by the LOGPREFIX (in shorewall6.conf(5)).
For the remaining columns, see shorewall6-rules (5).
Drop Teredo packets from the net.
DROP net:[2001::/32] all
Don't subject packets from 2001:DB8::/64 to the remaining rules in
WHITELIST net:[2001:DB8::/64] all
