We all know that a Firewall works on the stated rules. Depending upon the requirements, these rules can be added or omitted from the set of Firewall rules. However, at times, you accidentally add a Firewall rule, or you might not need a certain Firewall rule any longer. In both of these cases, you would feel the need to remove that particular rule. Therefore, in this article, we will teach you how you can remove a UFW rule.
How to Remove a UFW Rule

$ sudo ufw allow 53/tcp

Now, we will attempt to remove the very same Firewall rule. For that, we will run the following command:
$ sudo ufw delete allow 53/tcp

By following this very basic yet useful guide, you can quickly remove any UFW rule that you want. All you need to know is the exact rule or its associated number, and you can easily remove any UFW rule of your choice whenever you want.
