Issue with usage of ufw (Linux Firewall)

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

@Dhruv ,

Thanks Dhruv for posting on the forum! Team is working on it.
Will get back to you soon.


  1. Please install required modules with these commands.
    sudo apt update 
    sudo apt install kernel-modules-iptables
  2. Reboot the brainypi and it should work.

Please get back if anything.
