       firewalld.policy - firewalld policy configuration files

SYNOPSIS

       /etc/firewalld/policies/policy.xml

       /usr/lib/firewalld/policies/policy.xml

DESCRIPTION

       A firewalld policy configuration file contains the information for a policy. These are the
       policy descriptions, services, ports, protocols, icmp-blocks, masquerade, forward-ports
       and rich language rules in an XML file format. The file name has to be policy_name.xml
       where length of policy_name is currently limited to 17 chars.

       This is the structure of a policy configuration file:

           <?xml version="1.0" encoding="utf-8"?>
           <policy [version="versionstring"] [target="CONTINUE|ACCEPT|REJECT|DROP"] [priority="priority"]>
               [ <ingress-zone name="zone"/> ]
               [ <egress-zone name="zone"/> ]

               [ <short>short description</short> ]
               [ <description>description</description> ]
               [ <service name="string"/> ]
               [ <port port="portid[-portid]" protocol="tcp|udp|sctp|dccp"/> ]
               [ <protocol value="protocol"/> ]
               [ <icmp-block name="string"/> ]

               [

                       [ <destination address="address[/mask]"|ipset="ipset" [invert="True"]/> ]
                       [

                       ]
                       [
                           <log [prefix="prefix text"] [level="emerg|alert|crit|err|warn|notice|info|debug"]> [<limit value="rate/duration"/>] </log> |

                       [

                           <reject [type="rejecttype"]> [<limit value="rate/duration"/>] </reject> |
                           <drop> [<limit value="rate/duration"/>] </drop> |
                           <mark set="mark[/mask]"> [<limit value="rate/duration"/>] </mark>
                       ]
                   </rule>
               ]

           </policy>

       The config can contain these tags and attributes. Some of them are mandatory, others
       optional.

   policy
       The mandatory policy start and end tag defines the policy. This tag can only be used once
       in a policy configuration file. There are optional attributes for policy:

       version="string"
           To give the policy a version.

       target="CONTINUE|ACCEPT|REJECT|DROP"
           Can be used to accept, reject or drop every packet that doesn't match any rule (port,
           service, etc.). The CONTINUE is the default and used for policies that are
           non-terminal.

   ingress-zone
       An optional element that can be used several times. It can be the name of a firewalld zone
       or one of the symbolic zones: HOST, ANY. See firewalld.policies(5) for information about
       symbolic zones.

   egress-zone
       An optional element that can be used several times. It can be the name of a firewalld zone
       or one of the symbolic zones: HOST, ANY. See firewalld.policies(5) for information about
       symbolic zones.

   short
       Is an optional start and end tag and is used to give a more readable name.

   description
       Is an optional start and end tag to have a description.

   service
       Is an optional empty-element tag and can be used several times to have more than one
       service entry enabled. A service entry has exactly one attribute:

       name="string"
           The name of the service to be enabled. To get a list of valid service names
           firewall-cmd --get-services can be used.

   port
       Is an optional empty-element tag and can be used several times to have more than one port
       entry. All attributes of a port entry are mandatory:

       port="portid[-portid]"
           The port can either be a single port number portid or a port range portid-portid.

       protocol="tcp|udp|sctp|dccp"
           The protocol can either be tcp, udp, sctp or dccp.

   protocol
       Is an optional empty-element tag and can be used several times to have more than one
       protocol entry. All protocol has exactly one attribute:

       value="string"
           The protocol can be any protocol supported by the system. Please have a look at
           /etc/protocols for supported protocols.

   icmp-block
       Is an optional empty-element tag and can be used several times to have more than one
       icmp-block entry. Each icmp-block tag has exactly one mandatory attribute:

       name="string"
           The name of the Internet Control Message Protocol (ICMP) type to be blocked. To get a
           list of valid ICMP types firewall-cmd --get-icmptypes can be used.

   masquerade
       Is an optional empty-element tag. It can be used only once. If it's present masquerading
       is enabled.

   forward-port
       Is an optional empty-element tag and can be used several times to have more than one port
       or packet forward entry. There are mandatory and also optional attributes for forward
       ports:

       Mandatory attributes:
           The local port and protocol to be forwarded.

           port="portid[-portid]"
               The port can either be a single port number portid or a port range portid-portid.

           protocol="tcp|udp|sctp|dccp"
               The protocol can either be tcp, udp, sctp or dccp.

       Optional attributes:
           The destination of the forward. For local forwarding add to-port only. For remote
           forwarding add to-addr and use to-port optionally if the destination port on the
           destination machine should be different.

           to-port="portid[-portid]"
               The destination port or port range to forward to. If omitted, the value of the
               port= attribute will be used altogether with the to-addr attribute.

           to-addr="address"
               The destination IP address either for IPv4 or IPv6.

   source-port
       Is an optional empty-element tag and can be used several times to have more than one
       source port entry. All attributes of a source port entry are mandatory:

       port="portid[-portid]"
           The port can either be a single port number portid or a port range portid-portid.

       protocol="tcp|udp|sctp|dccp"
           The protocol can either be tcp, udp, sctp or dccp.

   rule
       Is an optional element tag and can be used several times to have more than one rich
       language rule entry.

       The general rule structure:

           <rule [family="ipv4|ipv6"] [priority="priority"]>
               [ <source address="address[/mask]"|mac="MAC"|ipset="ipset" [invert="True"]/> ]
               [ <destination address="address[/mask]"|ipset="ipset" [invert="True"]/> ]
               [
                   <service name="string"/> |

                   <log [prefix="prefix text"] [level="emerg|alert|crit|err|warn|notice|info|debug"]> [<limit value="rate/duration"/>] </log> |
                   <nflog [group="group id"] [prefix="prefix text"] [queue-size="threshold"]> [<limit value="rate/duration"/>] </nflog>
               ]
               [ <audit> [<limit value="rate/duration"/>] </audit> ]
               [
                   <accept> [<limit value="rate/duration"/>] </accept> |

                   <mark set="mark[/mask]"> [<limit value="rate/duration"/>] </mark>
               ]
           </rule>

       Rule structure for source black or white listing:

           <rule [family="ipv4|ipv6"] [priority="priority"]>
               <source address="address[/mask]"|mac="MAC"|ipset="ipset" [invert="True"]/>
               [
                   <log [prefix="prefix text"] [level="emerg|alert|crit|err|warn|notice|info|debug"]> [<limit value="rate/duration"/>] </log> |
                   <nflog [group="group id"] [prefix="prefix text"] [queue-size="threshold"]> [<limit value="rate/duration"/>] </nflog>
               ]
               [ <audit> [<limit value="rate/duration"/>] </audit> ]
               <accept> [<limit value="rate/duration"/>] </accept> |
               <reject [type="rejecttype"]> [<limit value="rate/duration"/>] </reject> |
               <drop> [<limit value="rate/duration"/>] </drop>
