What is the Default to Purism Firewall?

Software PureOS
,
1

Under “Network Connections” in “Editing” at the “General” tab, where it says “Firewall zone” and the drop down is set to “Default”

What does Default represent?

  • DMZ

  • external

  • home

  • internal

  • public

  • trusted

Which of these is the actual “Default”?

This is a very good question. I don’t know what I don’t know but… …It doesn’t seem like there is any firewall.

root@pureos:~# firewall-cmd
-bash: firewall-cmd: command not found
root@pureos:~# apt list --installed | grep -i fire

root@pureos:~# apt list --installed | grep -i ufw
root@pureos:~# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

I opened a port with netcat -l 23 and when I used nmap -sS x.x.x.x from another machine it showed port 23 as open. Seems like no firewall to me. Perhaps someone could tell us what we need to install to get a working firewall. Perhaps firewalld?

So the default is “none”?

In the graphical user interface it gives me that list I typed as bullet points (and more options)
