Because deleting rules in UFW can be a little bit annoying this little trick will make your life much easier. Instead of using this syntax:

ufw delete allow 80/tcp

use this syntax:

ufw delete ####

where #### is the number of your firewall rule.

The numbers of your firewall rules can listed using:

ufw status numbered

A possible output could be:

Status: active

     To                         Action      From
     --                         ------      ----
[ 1] 80/tcp                     ALLOW IN    Anywhere
[ 2] 443/tcp                    ALLOW IN    Anywhere

  1. Thank you that was helpful

    Just wondering if there is a way to delete multiple ports at the same time

  2. What do you mean with multiple ports, multiple rules?

  3. Very helpful!


  5. Nice

  6. So helpful. Thank-you! I made a mistake entering a rule and could not figure out the syntax to remove the messed up rule. Using the number saved my day. Thanks again!

  7. Thanks, saved my day

  8. Very useful! Ansible has nice methods to add ufw rules but not to delete them 🙁
