Is anyone able to assist with explaining (or providing a link towards explaining) how to read iptables’ tables?
I am trying to understand the interactions regarding tables, chains, and rules - but I’m having problems understanding the readout from the “iptables-S” command.
I’m personally interested in what do the “-P,” “-N,” and “-A” signify.
I’m also curious as to what the “LIBVIRT_INP,” “LIBVIRT_FWI,” AND “LIBVIRT_FWX” chains are all about…
I am referencing the man pages, and checking online:
…but I may be missing/overlooking something.
While explanation would be helpful, if one could offer an article for instruction, that would be awesome.
