Before we discuss removing the rules, let’s just take a brief look at what the Firewalld rules are used for.

These rules mainly manage what traffic must be allowed. Also, we can create the rules either temporarily or permanently. Now, let’s see how we can remove the rules from firewalld.

We can remove the firewalld rules in two different ways.


By editing the XML file

All the firewalld rules are stored in a direct.xml file. And it is present in the path /etc/firewalld/direct.xml. So we can edit this file to remove the rules.

We edit this file either using vi editor or nano editor. Then we can remove the rules by commenting on the lines or simply deleting them.


Through commands

We can also remove the rules via commands.

Here is the syntax to remove the rules temporarily,

firewall-cmd --direct --remove-rule ...

And here is the syntax to remove the rules permanently,

firewall-cmd [--permanent] --direct --remove-rules { ipv4 | ipv6 | eb } table chain


How we remove FirewallD rule?

Recently, one of our customers approached us to delete the firewalld rules.

Now, let’s see how our Support Engineers remove the rules from the firewalld.

Initially, we checked the current rules in firewalld by running the command,

firewall-cmd --direct --get-rules ipv4 filter IN_public_allow

After that, we ran the below command to remove the rule provided by the customer.

firewall-cmd --direct --remove-rule ipv4 filter IN_public_allow 0 -m tcp -p tcp --dport 25 -j ACCEPT

This successfully removed the rule.
