Is there a way to kill off firewall for good. It keeps turning on randomly, after booting and upgrading???
You must disable the service or it will be back on reboot.
I would advise against that.
Take it from nearly 20 years of running asterisk experience, it’s not a good idea.
Asterisk systems are highly targeted and when found heavily exploited.
Most of us are using static addresses which makes it worse. Once discovered, we can always be found.
At a minimum when you have about 10 hackers trying to just probe/discover your dialplan, you loose bandwidth for everything else. More critical for those of us who do this in a more minimal resource wise. But often they do their probing at night when you are not watching by script. If you are not watching at CLI> you might not see anything. Watch your logs.
And that is not to mention the OS. Hackers know the latest exploits way before you do and being that there is a fix/patch for it yet?
Take some time to just learn how to use it better. It pays.
I guess I do not understand why I need it, my router does my firewall?
@DavidKG5RDF If you are running in a VM in the Cloud you absolutely need a firewall.
If you are just running on a Pi device on your local network, then yeah your router is the public facing interface and you can run your firewall there.
If you are running an ASL3 appliance this is how you disable the firewall:
sudo systemctl stop firewalld
sudo systemctl disable firewalld
