My server does not use FTP, why can't I delete firewall rule 20,21 and 39000-40000port?
I keep deleting, it keeps repeating, ....
kevins Distro please
I test it can be deleted ~ What linux distribution do you use?
centos 7.5，I keep deleting, the rule is automatically created again and again！
Can I log in to your panel and check? After I deleted these ports on several test servers, it didn't automatically add them again.
sure,add you now please check
