OS: Linux Mint 18.2 Cinnamon 64-bit
Let's start with the status of ufw:
sudo ufw status says:
Status: inactive
Hence, I suppose, in spite there is connection between ufw and iptables, if I am using iptables for controlling open ports, etc., I do not need it.
Is this assumption correct, and I can freely purge ufw from my systems?
Or is there any reason on keeping it?
