Hi,
I would dare to say without any sarcasm the same way you turned it on,
as far as I know no firewall is installed by default in debian/devuan
and a default install (desktop, sever, minimal, netinstall) has all
ports open unless you install at least iptables*.
I would recommend you to try arno-iptables-firewall, i use it on
every box, be it desktop, server or router, it is easy to setup
as it has a builtin config frontend (but it could be tweaked
at your liking by editing the config files).
Starting it is as easy as:

service arno-iptables-firewall start

to stop:

service arno-iptables-firewall stop

to reconfigure

dpkg-reconfigure arno-iptables-firewall

Hope this helps.
Ciao,
Tito
