firewalld.direct(5)

NAME

   firewalld.direct - firewalld direct configuration file

SYNOPSIS

   /etc/firewalld/direct.xml

DESCRIPTION

   Direct configuration gives a more direct access to the firewall. It
   requires user to know basic ip(6)tables/ebtables concepts, i.e.  table
   (filter/mangle/nat/...), chain (INPUT/OUTPUT/FORWARD/...), commands
   (-A/-D/-I/...), parameters (-p/-s/-d/-j/...) and targets
   (ACCEPT/DROP/REJECT/...). Direct configuration should be used only as a
   last resort when it's not possible to use firewalld.zone(5). See also
   Direct Options in firewall-cmd(1).

   A firewalld direct configuration file contains informations about
   permanent direct chains, rules and passthrough ...

   This is the structure of a direct configuration file:

       <?xml version="1.0" encoding="utf-8"?>
       <direct>
         [ <chain ipv="ipv4|ipv6|eb" table="table" chain="chain"/> ]
         [ <rule ipv="ipv4|ipv6|eb" table="table" chain="chain" priority="priority"> args </rule> ]
         [ <passthrough ipv="ipv4|ipv6|eb"> args </passthrough> ]
       </direct>

   direct
   The mandatory direct start and end tag defines the direct. This tag can
   only be used once in a direct configuration file. There are no
   attributes for direct.

   chain
   Is an optional empty-element tag and can be used several times. It can
   be used to define names for additional chains. A chain entry has
   exactly three attributes:

   ipv="ipv4|ipv6|eb"
       The IP family where the chain will be created. This can be either
       ipv4, ipv6 or eb.

   table="table"
       The table name where the chain will be created. This can be one of
       the tables that can be used for iptables, ip6tables or ebtables.
       For the possible values, see TABLES section in the iptables,
       ip6tables or ebtables man pages.

   chain="chain"
       The name of the chain, that will be created. Please make sure that
       there is no other chain with this name already.

   Please remember to add a rule or passthrough rule with an --jump or
   --goto option to connect the chain to another one.

   rule
   Is an optional element tag and can be used several times. It can be
   used to add rules to a built-in or added chain. A rule entry has
   exactly four attributes:

   ipv="ipv4|ipv6|eb"
       The IP family where the rule will be added. This can be either
       ipv4, ipv6 or eb.

   table="table"
       The table name where the rule will be added. This can be one of the
       tables that can be used for iptables, ip6tables or ebtables. For
       the possible values, see TABLES section in the iptables, ip6tables
       or ebtables man pages.

   chain="chain"
       The name of the chain where the rule will be added. This can be
       either a built-in chain or a chain that has been created with the
       chain tag. If the chain name is a built-in chain, then the rule
       will be added to chain_direct, else the supplied chain name is
       used.  chain_direct is created internally for all built-in chains
       to make sure that the added rules do not conflict with the rules
       created by firewalld.

   priority="priority"
       The priority is used to order rules. Priority 0 means add rule on
       top of the chain, with a higher priority the rule will be added
       further down. Rules with the same priority are on the same level
       and the order of these rules is not fixed and may change. If you
       want to make sure that a rule will be added after another one, use
       a low priority for the first and a higher for the following.

   The args can be any arguments of iptables or ip6tables, that do not
   conflict with the table or chain attributes.

   passthrough
   Is an optional element tag and can be used several times. It can be
   used to add rules to a built-in or added chain. A rule entry has
   exactly one attribute:

   ipv="ipv4|ipv6|eb"
       The IP family where the passthrough rule will be added. This can be
       either ipv4, ipv6 or eb.

   The args can be any arguments of iptables or ip6tables.

   The passthrough rule will be added to the chain directly. There is no
   mechanism like for the direct rule above. The user of the passthrough
   rule has to make sure that there will be no conflict with the rules
   created by firewalld.

EXAMPLE

   Blacklisting of the networks 192.168.1.0/24 and 192.168.5.0/24 with
   logging and dropping early in the raw table:

       <?xml version="1.0" encoding="utf-8"?>
       <direct>
         <chain ipv="ipv4" table="raw" chain="blacklist"/>
         <rule ipv="ipv4" table="raw" chain="PREROUTING" priority="0">-s 192.168.1.0/24 -j blacklist</rule>
         <rule ipv="ipv4" table="raw" chain="PREROUTING" priority="1">-s 192.168.5.0/24 -j blacklist</rule>
         <rule ipv="ipv4" table="raw" chain="blacklist" priority="0">-m limit --limit 1/min -j LOG --log-prefix "blacklisted: "</rule>
         <rule ipv="ipv4" table="raw" chain="blacklist" priority="1">-j DROP</rule>
       </direct>
