Hi! I use Ispcofig3 + debian10 (buster) with ufw. If i add a port to Ispconfig's firevall, than its opens the port until I reboot. The port number doesn't disappear from ispconfig's firewall, but port is closed after I reboot the computer. If I use this command from terminal Code: sudo ufw allow 1234 than 1234 port is permanently opened after reboot too. It is interesting. Any idea, how to solve this?
