NAME
firewalld.service - firewalld service configuration files
SYNOPSIS
/etc/firewalld/services/service.xml /usr/lib/firewalld/services/service.xml
DESCRIPTION
A firewalld service configuration file provides the information of a service entry for firewalld. The most important configuration options are ports, modules and destination addresses.
This example configuration file shows the structure of a service configuration file:
<?xml version="1.0" encoding="utf-8"?> <service> <short>My Service</short> <description>description</description> <port port="137" protocol="tcp"/> <protocol value="igmp"/> <module name="nf_conntrack_netbios_ns"/> <destination ipv4="224.0.0.251" ipv6="ff02::fb"/> <include service="ssdp"/> <helper name="ftp"/> </service>
OPTIONS
The config can contain these tags and attributes. Some of them are mandatory, others optional.
service
The mandatory service start and end tag defines the service. This tag can only be used once in a service configuration file. There are optional attributes for services:
version="string"
short
Is an optional start and end tag and is used to give an service a more readable name.
description
Is an optional start and end tag to have a description for a service.
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="string"
protocol="string"
For compatibility with older firewalld versions, it is possible to add protocols with the port option where the port is empty. With the addition of native protocol support in the service, this it not needed anymore. These entries will automatically be converted to protocols. With the next modification of the service file, the enries will be listed as protocols.
protocol
Is an optional empty-element tag and can be used several times to have more than one protocol entry. A protocol entry has exactly one attribute:
value="string"
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="string"
protocol="string"
module
This element is deprecated. Please use helper described below in the section called “helper”.
destination
Is an optional empty-element tag and can be used only once. The destination specifies the destination network as a network IP address (optional with /mask), or a plain IP address. The use of hostnames is not recommended, because these will only be resolved at service activation and transmitted to the kernel. For more information in this element, please have a look at --destination in iptables(8) and ip6tables(8).
ipv4="address[/mask]"
ipv6="address[/mask]"
include
Is an optional empty-element tag and can be used several times to have more than one include entry. An include entry has exactly one attribute:
service="string"
Warning:Firewalld will only check that the included service is a valid service if it's applied to a zone.
helper
Is an optional empty-element tag and can be used several times to have more than one helper entry. An helper entry has exactly one attribute:
name="string"
