I have installed Virtualmin behind pfsense firewall and I want to control all incoming and outgoing traffic from there. I tried to disable FirewallD and Linux Firewall but when I restart all coming back online again.
How to permanently disable or remove if that possible those firewalls
I don’t understand them and I don’t need to
I didn’t know firewalld was even used on Ubuntu. Last time I used it it used something called ufw, which I’m guessing stands for Ubuntu firewall. Have you tried checking the ufw status?
$ sudo ufw status
You may be trying to disable something that doesn’t exist.
