This is the summary of the work done by Shekhar Sharma for the netfilter project during the Google Summer of Code 2019.
My work was concentrated over the command line tool 'nftables', built and maintained by the netfilter organisation as the successor to 'iptables'. I primarily focused on strengthening the testing infrastructure and extending the GeoIP feature for nftables.
Nftables is a command line tool which enables the users to configure their firewall by building tables,chains and rules to filter the packets that flow through the computer.
To install nftables, one can clone the repository from this link.
git clone https://git.netfilter.org/nftables/
