[webmin-l] iptables not restore upon reboot on Ubuntu 20.04.LTS

[Joaquim H. <jo...@we...>]

Not sure if this has been posted here before, but we have a couple of 
Ubuntu 20.04.LTS servers where Webmin will *not* restore IPTABLES upon 
re-boot.

If I go into Webmin > Networking > Linux Firewall, it says it should 
activate on boot time, but it won't.

I can, naturally, do an iptables-restore < 
/etc/webmin/firewall/iptables.save, but it's not quite as "sexy" ;-)


What am I doing wrong?
