NFTables To Replace iptables In the Linux Kernel
From the YALF (Yet Another Linux Firewall) department on Slashdot http://linux.slashdot.org/story/13/1...-linux-kernel:
"NFTables is queued up for merging into the Linux 3.13 kernel. NFTables is a four-year-old project by the creators of Netfilter to write a new packet filtering / firewall engine for the Linux kernel to deprecate iptables (though it now offers an iptables compatibility layer too). NFTables promises to be more powerful, simpler, reduce code complication, improve error reporting, and provide more efficient handling of packet filter rules. The code was merged into net-next for the Linux 3.13 kernel. Iptables will still be present until NFTables is finished, but it is possible to try it out now. LWN also has a writeup on NFTables."
You don't need to be a genius to debug a pf.conf firewall ruleset, you just need the guts to run tcpdump
