014.01.56.4. The text introduces iptables as the system for creating and manipulating firewall rules in Linux. Are there alternative systems mentioned, and what is the status of iptables compared to newer systems like nftables and bpfilter?
Yes, there are alternative systems available, such as nftables that is meant to replace iptables. The command used to administer nftables is nft, and there's an iptables-to-nftables translator called iptables translate. There's another system much more complicated than it called as bpfilter. Iptables is still the most widely used system compared to the newer ones.
