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
Thank you that was helpful
Just wondering if there is a way to delete multiple ports at the same time
What do you mean with multiple ports, multiple rules?
Very helpful!
THANKS
Nice
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!
Thanks, saved my day
Very useful! Ansible has nice methods to add ufw rules but not to delete them 🙁
Thank you. I need this article.
Care for the following. When you remove a rule, having number 1, be aware that the numbering will change for the rules that are still active.
So if I have for example:
To Action From -- ------ ---- [ 1] 22 ALLOW IN Anywhere [ 2] 443 ALLOW IN Anywhere [ 3] 80 (v6) DENY IN Anywhere (v6) [ 4] 8080 (v6) ALLOW IN Anywhere (v6) [ 5] 8443 (v6) ALLOW IN Anywhere (v6)If I wish to remove rule #3 and #4, I should execute `sudo ufw delete 3` followed by the same command, instead of `sudo ufw delete 4`.
PS. I’m sorry if the code-blocks look messed up. I didn’t take time to figure out the syntax on this website.
Helpful, Thank you!
Thanks, it was very helpful.
