What is Netfilter and what is it used for?
Hello everyone,
I am new to Linux and I have been reading about Netfilter and iptables. I understand that iptables is a firewall program that is used to define and manage firewall rules, but I am not sure what Netfilter is and what it is used for.
Can someone please explain what Netfilter is and how it is related to iptables? Also, what are some common use cases for Netfilter?
Thank you in advance for your help.
