-Firewall Configuration (Deprecated)
-###################################
-
-.. note:: **Important note:**
-   This documentation is valid only for VyOS Sagitta prior to
-   1.4-rolling-202308040557
-
-********
-Overview
-********
-
-VyOS makes use of Linux `netfilter <https://netfilter.org/>`_ for packet
-filtering.
-
-The firewall supports the creation of groups for ports, addresses, and
-networks (implemented using netfilter ipset) and the option of interface
-or zone based firewall policy.
-
-.. note:: **Important note on usage of terms:**
-   The firewall makes use of the terms `in`, `out`, and `local`
-   for firewall policy. Users experienced with netfilter often confuse
-   `in` to be a reference to the `INPUT` chain, and `out` the `OUTPUT`
-   chain from netfilter. This is not the case. These instead indicate
-   the use of the `FORWARD` chain and either the input or output
-   interface. The `INPUT` chain, which is used for local traffic to the
-   OS, is a reference to as `local` with respect to its input interface.
-
-
-***************
-Global settings
-***************
-
-Some firewall settings are global and have an affect on the whole system.
-
-.. cfgcmd:: set firewall all-ping [enable | disable]
-
-   By default, when VyOS receives an ICMP echo request packet destined for
-   itself, it will answer with an ICMP echo reply, unless you avoid it
-   through its firewall.
-
-   With the firewall you can set rules to accept, drop or reject ICMP in,
-   out or local traffic. You can also use the general **firewall all-ping**
-   command. This command affects only to LOCAL (packets destined for your
-   VyOS system), not to IN or OUT traffic.
-
-   .. note:: **firewall all-ping** affects only to LOCAL and it always
-      behaves in the most restrictive way
-
-   .. code-block:: none
-
-      set firewall all-ping enable
-
-   When the command above is set, VyOS will answer every ICMP echo request
-   addressed to itself, but that will only happen if no other rule is
-   applied dropping or rejecting local echo requests. In case of conflict,
-   VyOS will not answer ICMP echo requests.
-
-   .. code-block:: none
-
-      set firewall all-ping disable
-
-   When the command above is set, VyOS will answer no ICMP echo request
-   addressed to itself at all, no matter where it comes from or whether
-   more specific rules are being applied to accept them.
-
-.. cfgcmd:: set firewall broadcast-ping [enable | disable]

-******
-Groups
-******
-
-Firewall groups represent collections of IP addresses, networks, ports,
-mac addresses or domains. Once created, a group can be referenced by
-firewall, nat and policy route rules as either a source or destination
-matcher. Members can be added or removed from a group without changes to,
-or the need to reload, individual firewall rules.
-
-Groups need to have unique names. Even though some contain IPv4
-addresses and others contain IPv6 addresses, they still need to have
-unique names, so you may want to append "-v4" or "-v6" to your group
-names.
-
-
-Address Groups
-==============
-
-In an **address group** a single IP address or IP address ranges are
-defined.
-
-.. cfgcmd::  set firewall group address-group <name> address [address |
-   address range]
-.. cfgcmd::  set firewall group ipv6-address-group <name> address <address>
-
-   Define a IPv4 or a IPv6 address group
-
-   .. code-block:: none
-
-      set firewall group address-group ADR-INSIDE-v4 address 192.168.0.1
-      set firewall group address-group ADR-INSIDE-v4 address 10.0.0.1-10.0.0.8
-      set firewall group ipv6-address-group ADR-INSIDE-v6 address 2001:db8::1
-
-.. cfgcmd::  set firewall group address-group <name> description <text>
-.. cfgcmd::  set firewall group ipv6-address-group <name> description <text>
-
-   Provide a IPv4 or IPv6 address group description
-
-Network Groups
-==============
-
-While **network groups** accept IP networks in CIDR notation, specific
-IP addresses can be added as a 32-bit prefix. If you foresee the need
-to add a mix of addresses and networks, the network group is
-recommended.
-
-.. cfgcmd::  set firewall group network-group <name> network <CIDR>
-.. cfgcmd::  set firewall group ipv6-network-group <name> network <CIDR>
-
-   Define a IPv4 or IPv6 Network group.
-
-   .. code-block:: none
-
-      set firewall group network-group NET-INSIDE-v4 network 192.168.0.0/24
-      set firewall group network-group NET-INSIDE-v4 network 192.168.1.0/24
-      set firewall group ipv6-network-group NET-INSIDE-v6 network 2001:db8::/64
-
-.. cfgcmd::  set firewall group network-group <name> description <text>
-.. cfgcmd::  set firewall group ipv6-network-group <name> description <text>
-
-   Provide a IPv4 or IPv6 network group description.
-
-Port Groups
-===========
-
-A **port group** represents only port numbers, not the protocol. Port
-groups can be referenced for either TCP or UDP. It is recommended that
-TCP and UDP groups are created separately to avoid accidentally
-filtering unnecessary ports. Ranges of ports can be specified by using
-`-`.
-
-.. cfgcmd:: set firewall group port-group <name> port
-   [portname | portnumber | startport-endport]
-
-   Define a port group. A port name can be any name defined in
-   /etc/services. e.g.: http
-
-   .. code-block:: none
-
-      set firewall group port-group PORT-TCP-SERVER1 port http
-      set firewall group port-group PORT-TCP-SERVER1 port 443
-      set firewall group port-group PORT-TCP-SERVER1 port 5000-5010
-
-.. cfgcmd:: set firewall group port-group <name> description <text>
-
-   Provide a port group description.
-
-MAC Groups
-==========
-
-A **mac group** represents a collection of mac addresses.
-
-.. cfgcmd::  set firewall group mac-group <name> mac-address <mac-address>
-
-   Define a mac group.
-
-.. code-block:: none
-
-      set firewall group mac-group MAC-G01 mac-address 88:a4:c2:15:b6:4f
-      set firewall group mac-group MAC-G01 mac-address 4c:d5:77:c0:19:81
-
-
-Domain Groups
-=============
-
-A **domain group** represents a collection of domains.
-
-.. cfgcmd::  set firewall group domain-group <name> address <domain>
-
-   Define a domain group.
-
-.. code-block:: none
-
-      set firewall group domain-group DOM address example.com
-
-
-*********
-Rule-Sets
-*********
-
-A rule-set is a named collection of firewall rules that can be applied
-to an interface or a zone. Each rule is numbered, has an action to apply
-if the rule is matched, and the ability to specify the criteria to
-match. Data packets go through the rules from 1 - 999999, at the first match
-the action of the rule will be executed.
-
-.. cfgcmd:: set firewall name <name> description <text>
-.. cfgcmd:: set firewall ipv6-name <name> description <text>
-
-   Provide a rule-set description.
-
-.. cfgcmd:: set firewall name <name> default-action [accept | drop | jump |
-   reject | return]
-.. cfgcmd:: set firewall ipv6-name <name> default-action [accept | drop |
-   jump | reject | return]
-
-   This set the default action of the rule-set if no rule matched a packet
-   criteria. If defacult-action is set to ``jump``, then
-   ``default-jump-target`` is also needed.
-
-.. cfgcmd:: set firewall name <name> default-jump-target <text>
-.. cfgcmd:: set firewall ipv6-name <name> default-jump-target <text>
-
-   To be used only when ``defult-action`` is set to ``jump``. Use this
-   command to specify jump target for default rule.
-
-.. cfgcmd:: set firewall name <name> enable-default-log
-.. cfgcmd:: set firewall ipv6-name <name> enable-default-log
-
-   Use this command to enable the logging of the default action.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> action [accept | drop |
-   jump | queue | reject | return]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> action [accept |
-   drop | jump | queue | reject | return]
-
-   This required setting defines the action of the current rule. If action
-   is set to ``jump``, then ``jump-target`` is also needed.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> jump-target <text>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> jump-target <text>
-
-   To be used only when ``action`` is set to ``jump``. Use this
-   command to specify jump target.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> queue <0-65535>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> queue <0-65535>
-
-   Use this command to set the target to use. Action queue must be defined
-   to use this setting
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> queue-options
-   <bypass-fanout>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> queue-options
-   <bypass-fanout>
-
-   Options used for queue target. Action queue must be defined to use this
-   setting
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> description <text>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> description <text>
-
-   Provide a description for each rule.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> log [disable | enable]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> log [disable |
-   enable]
-
-   Enable or disable logging for the matched packet.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> log-options level
-   [emerg | alert | crit | err | warn | notice | info | debug]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> log-options level
-   [emerg | alert | crit | err | warn | notice | info | debug]
-
-   Define log-level. Only applicable if rule log is enable.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> log-options group
-   <0-65535>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> log-options group
-   <0-65535>
-
-   Define log group to send message to. Only applicable if rule log is enable.

-.. cfgcmd:: set firewall name <name> rule <1-999999> log-options snaplen
-   <0-9000>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> log-options snaplen
-   <0-9000>
-
-   Define length of packet payload to include in netlink message. Only
-   applicable if rule log is enable and log group is defined.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> log-options
-   queue-threshold <0-65535>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> log-options

-
-   Define number of packets to queue inside the kernel before sending them to
-   userspace. Only applicable if rule log is enable and log group is defined.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> disable
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> disable
-
-   If you want to disable a rule but let it in the configuration.
-
-Matching criteria
-=================
-
-There are a lot of matching criteria against which the package can be tested.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> connection-status nat
-   [destination | source]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> connection-status
-   nat [destination | source]
-
-   Match criteria based on nat connection status.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> connection-mark
-   <1-2147483647>
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> connection-mark
-   <1-2147483647>
-
-   Match criteria based on connection mark.
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> source address
-   [address | addressrange | CIDR]
-.. cfgcmd:: set firewall name <name> rule <1-999999> destination address
-   [address | addressrange | CIDR]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> source address
-   [address | addressrange | CIDR]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> destination address
-   [address | addressrange | CIDR]
-
-   This is similar to the network groups part, but here you are able to negate
-   the matching addresses.
-
-   .. code-block:: none
-
-      set firewall name WAN-IN-v4 rule 100 source address 192.0.2.10-192.0.2.11
-      # with a '!' the rule match everything except the specified subnet
-      set firewall name WAN-IN-v4 rule 101 source address !203.0.113.0/24
-      set firewall ipv6-name WAN-IN-v6 rule 100 source address 2001:db8::202
-
-.. cfgcmd:: set firewall name <name> rule <1-999999> source address-mask
-   [address]
-.. cfgcmd:: set firewall name <name> rule <1-999999> destination address-mask
-   [address]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> source address-mask
-   [address]
-.. cfgcmd:: set firewall ipv6-name <name> rule <1-999999> destination
-   address-mask [address]
-
-   An arbitrary netmask can be applied to mask addresses to only match against
-   a specific portion. This is particularly useful with IPv6 and a zone-based
-   firewall as rules will remain valid if the IPv6 prefix changes and the host
-   portion of systems IPv6 address is static (for example, with SLAAC or
-   `tokenised IPv6 addresses
-   <https://datatracker.ietf.org/doc/id/draft-chown-6man-tokenised-ipv6-identifiers-02.txt>`_).
-
-   This functions for both individual addresses and address groups.
-
-   .. stop_vyoslinter
-   .. code-block:: none
-
-      # Match any IPv6 address with the suffix ::0000:0000:0000:beef

-***********************************
-Applying a Rule-Set to an Interface
-***********************************
-
-A Rule-Set can be applied to every interface:
-
-* ``in``: Ruleset for forwarded packets on an inbound interface
-* ``out``: Ruleset for forwarded packets on an outbound interface
-* ``local``: Ruleset for packets destined for this router
-
-.. cfgcmd:: set firewall interface <interface> [in | out | local] [name |
-   ipv6-name] <rule-set>
-
-
-   Here are some examples for applying a rule-set to an interface
-
-   .. code-block:: none
-
-      set firewall interface eth1.100 in name LANv4-IN
-      set firewall interface eth1.100 out name LANv4-OUT
-      set firewall interface bond0 in name LANv4-IN
-      set firewall interface vtun1 in name LANv4-IN
-      set firewall interface eth2* in name LANv4-IN
-
-   .. note::
-      As you can see in the example here, you can assign the same rule-set to
-      several interfaces. An interface can only have one rule-set per chain.
-
-   .. note::
-      You can use wildcard ``*`` to match a group of interfaces.
