- -------------------
- Available actions:
- * add - add specified rule. See `Rule syntax` section below.
- * del - delete specified rule. The rule to remove can be selected either by rule number using :option:`--rule-no`
- or by specifying the rule itself using the same syntax used for adding it.
- * list - list all the rules for a given VM.
- * reset - remove all firewall rules and reset to default (accept all connections)
- Rule syntax
- -----------
- A single rule is built from:
- - action - either ``drop`` or ``accept``
- - zero or more matches
- Selected action is applied to packets when all specified matches match,
- further rules are not evaluated. If none of the rules match, the default
- firewall policy is ``drop``.
- Supported matches:
- - ``dsthost`` - destination host or network. Can be either IP address in CIDR
- notation, or a host name. Both IPv4 and IPv6 are supported by the rule syntax.
- In order to allow reuse of ``--raw`` output, ``dst4`` and ``dst6`` are accepted
- as synonyms.
- - ``dst4`` - see ``dsthost``
- - ``dst6`` - see ``dsthost``
- - ``proto`` - specific IP protocol. Supported values: ``tcp``, ``udp``,
- ``icmp``.
- - ``dstports`` - destination port or ports range. Can be either a single port
- or a range separated by ``-``. Valid only together with ``proto=udp`` or
- ``proto=tcp``.
- - ``icmptype`` - ICMP message type, specified as numeric value. Valid only
- together with ``proto=icmp``.
- - ``specialtarget`` - predefined target. Currently the only supported value is
- ``dns``. This can be combined with other matches to narrow it down.
- - ``expire`` - the rule matches only until the specified time and is then
- automatically removed. The time can be given either as number of seconds
- since 1/1/1970 or as ``+seconds``, a relative time (``+300`` means 5
- minutes from now).
