UFW wont delete rule
Solution 1
The correct syntax would be:
sudo ufw delete allow 9000
If you make a rule by the following:
sudo ufw allow 9000
Then the rule is allow 9000
. Now if you want to delete the rule:
sudo ufw delete rule
i.e.
sudo ufw delete allow 9000
Solution 2
The first step you can list all current rules by number:
$ sudo ufw status numbered
Then base on the listed numbers, you can delete rule by number. The number of the rule is shown in the leftmost column.
$ sudo ufw delete 2

I was testing something and added a rule to my firewall to allow port 9000. in retrospect, I should have just disabled it temporarily. anyhow, I went to remove the rule and it wont let me, it says rule not found.
$ sudo ufw delete 9000 ERROR: Could not find rule '9000'
but clearly, the rule is still active:
$ sudo ufw status verbose Status: active Logging: on (low) Default: deny (incoming), allow (outgoing), disabled (routed) New profiles: skip To Action From -- ------ ---- 80 ALLOW IN Anywhere 443 ALLOW IN Anywhere 9000 ALLOW IN Anywhere 80 (v6) ALLOW IN Anywhere (v6) 443 (v6) ALLOW IN Anywhere (v6) 9000 (v6) ALLOW IN Anywhere (v6)
I read the UFW help and it says you can delete a port number, but it doesn't happen. How can I remove the rule for port 9000 from UFW?

Anders about 9 yearsYou can also print the rules numbered from one and up(ufw status numbered?) . And then you can delete them by giving the number(ufw delete 3?). Don't forget to read the man page for ufw(8) if you don't remember the syntax.

Fabiola González over 7 yearsIt didn't help me. I get the following message: "Could not delete non-existent rule Could not delete non-existent rule (v6)" But when checking the status it still appears

Fabiola González over 7 yearsI found it out. Type sudo ufw status numbered. Then "sudo ufw delete # (number of rule, ex. 'sudo ufw delete 3')"
