How do i configure my own firewalld service?

amurleopard

The default services are located under /usr/lib/firewalld/services/

To add your own service copy an existing service and modify it.

# cd /etc/firewalld/services/
# cp /usr/lib/firewalld/services/ipp.xml /etc/firewalld/services/
# mv ipp.xml saltstack.xml

Make edits the saltstack.xml file for Heading, Description, Protocol, and Port number(s)

$ cat saltstack.xml
<?xml version="1.0" encoding="utf-8"?>
<service>
  <short>Saltstack</short>
  <description>The Salt master communicates with the minions using an AES-encrypted ZeroMQ connection. These communications are done over TCP ports 4505 and 4506, which need to be accessible on the master only. </description>
  <port protocol="tcp" port="4505"/>
  <port protocol="tcp" port="4506"/>
</service>

Reload the firewalld

$ sudo firewall-cmd --reload
success

Verify - see your service under the name you called it

$ sudo firewall-cmd --get-services
