shorewall6-actions (5) - Linux Manuals

Columns are:

NAME

The name of the action. ACTION names should begin with an upper-case letter to distinguish them from Shorewall-generated chain names and be composed of letters, digits or numbers. If you intend to log from the action then the name must be no longer than 11 characters in length if you use the standard LOGFORMAT.

OPTIONS

Added in Shorewall 4.5.10. Available options are:

audit

Added in Shorewall 5.0.7. When this option is specified, the action is expected to have at least two parameters; the first is a target and the second is either 'audit' or omitted. If the second is 'audit', then the first must be an auditable target (ACCEPT, DROP or REJECT).

builtin

Added in Shorewall 4.5.16. Defines the action as a rule target that is supported by your ip6tables but is not directly supported by Shorewall. The action may be used as the rule target in an INLINE rule in m[blue]shorewall6-rulesm[][1](5).

Beginning with Shorewall 4.6.0, the Netfilter table(s) in which the builtin can be used may be specified: filter, nat, mangle and raw. If no table name(s) are given, then filter is assumed. The table names follow builtin and are separated by commas; for example, "FOOBAR builtin,filter,mangle" would specify FOOBAR as a builtin target that can be used in the filter and mangle tables.

Beginning with Shorewall 4.6.4, you may specify the terminating option with builtin to indicate to the Shorewall optimizer that the action is terminating (the current packet will not be passed to the next rule in the chain).

inline

Causes the action body (defined in action.action-name) to be expanded in-line like a macro rather than in its own chain. You can list Shorewall Standard Actions in this file to specify the inline option.

Caution
Some of the Shorewall standard actions cannot be used in-line and will generate a warning and the compiler will ignore inline if you try to use them that way:

DropSmurfs

IfEvent

Invalid (Prior to Shorewall 4.5.13)

NotSyn (Prior to Shorewall 4.5.13)

RST (Prior to Shorewall 4.5.13)

TCPFlags

mangle

Added in Shorewall 5.0.7. Specifies that this action is to be used in m[blue]shorewall6-mangle(5)m[][2] rather than m[blue]shorewall6-rules(5)m[][3].

noinline

Causes any later inline option for the same action to be ignored with a warning.

nolog

Added in Shorewall 4.5.11. When this option is specified, the compiler does not automatically apply the log level and/or tag from the invocation of the action to all rules inside of the action. Rather, it simply sets the $_loglevel and $_logtag shell variables which can be used within the action body to apply those logging options only to a subset of the rules.

state={UNTRACKED|NEW|ESTABLISHED|RELATED|INVALID}

Added in Shorewall 5.0.7. Reserved for use by Shorewall in actions.std.

terminating

Added in Shorewall 4.6.4. When used with builtin, indicates that the built-in action is termiating (i.e., if the action is jumped to, the next rule in the chain is not evaluated).
