Hi! Was able to install ufw using the command ‘sudo apt install ufw’, however post installation on running ‘sudo ufw allow [portnumber]’ throws an error stating - FATAL: Module ip6_tables not found in directory /lib/modules/4.19.219shunyaos
- Please install required modules with these commands.
sudo apt update sudo apt install kernel-modules-iptables
- Reboot the brainypi and it should work.
Please get back if anything.
