NAME
       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"/> ]

       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"]/> ]

           <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> |
