firewalld change via XML file


Hello!
I have CentOS 7.6
Machine has two NICs; one NIC is assigned in public zone and second in trusted zone.
What I am trying to do is:
Code:
# firewall-cmd --permanent --zone=trusted --add-source=192.168.1.10
This works.

However, I am trying to figure out how to do this by XML file; zone config XML files are under: /etc/firewalld/zones, and there is trusted.xml

Code:
<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Trusted</short>
  <description>All network connections are accepted.</description>
  <interface name="ens224"/>
  <sources ip="192.168.1.10"/>
</zone>
With above in XML, I restarted firewalld service. However, output shows:

Code:
# firewall-cmd --zone=trusted --list-all
trusted (active)
  target: ACCEPT
  icmp-block-inversion: no
  interfaces: ens224
  sources: 
  services: 
  ports: 
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:
Trying to figure out what I am missing?

are you sure the xml is correct?


I grabbed a random manpage
https://www.systutorials.com/docs/li...irewalld.zone/
This is the structure of a zone configuration file:
Code:
    <?xml version="1.0" encoding="utf-8"?>
    <zone [version="versionstring"] [target="ACCEPT|%%REJECT%%|DROP"]>
      [ <short>short description</short> ]
      [ <description>description</description> ]
      [ <interface name="string"/> ]
      [ <source address="address[/mask]"|mac="MAC"|ipset="ipset"/> ]
      [ <service name="string"/> ]
      [ <port port="portid[-portid]" protocol="tcp|udp|sctp|dccp"/> ]
      [ <protcol value="protocol"/> ]
      [ <icmp-block name="string"/> ]
      [ <icmp-block-inversion/> ]
      [ <masquerade/> ]
      [ <forward-port port="portid[-portid]" protocol="tcp|udp|sctp|dccp" [to-port="portid[-portid]"] [to-addr="ipv4address"]/> ]
      [ <source-port port="portid[-portid]" protocol="tcp|udp|sctp|dccp"/> ]
      [
        <rule [family="ipv4|ipv6"]>
        [ <source address="address[/mask]"|mac="MAC"|ipset="ipset" [invert="True"]/> ]
        [ <destination address="address[/mask]" [invert="True"]/> ]
        [
          <service name="string"/> |
          <port port="portid[-portid]" protocol="tcp|udp|sctp|dccp"/> |
          <protocol value="protocol"/> |
          <icmp-block name="icmptype"/> |
          <icmp-type name="icmptype"/> |
          <masquerade/> |
          <forward-port port="portid[-portid]" protocol="tcp|udp|sctp|dccp" [to-port="portid[-portid]"] [to-addr="address"]/>
        ]
        [ <log [prefix="prefixtext"] [level="emerg|alert|crit|err|warn|notice|info|debug"]> [<limit value="rate/duration"/>] </log> ]
        [ <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> |
          <mark set="mark[/mask]"> [<limit value="rate/duration"/>] </mark>
        ]
        </rule>
      ]
    </zone>

Wow; Thank you!!

I had this:

Code:
  <sources ip="192.168.1.10"/>
Changed to this:

Code:
  <source address="192.168.1.10"/>

Now, it works (after --reload)!

Code:
# firewall-cmd --zone=trusted --list-all
trusted (active)
  target: default
  icmp-block-inversion: no
  interfaces: ens224
  sources: 192.168.1.10
  services: 
  ports: 
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

BTW: Here is my XML file (that works):


Code:
# cat trusted.xml
<?xml version="1.0" encoding="utf-8"?>
<zone>
  <short>Trusted</short>
  <description>All network connections are accepted.</description>
  <interface name="ens224"/>
  <source address="192.168.1.10"/>
</zone>
