Transition iptables to nftables
by Dynosaw3 from LinuxQuestions.org on (#4R4JP)
I'm doing a pre-study before taking the plunge and installing Debian Buster. This implies building a firewall in nftables, which is new to me.
We're talking of a simple stand-alone, domestic, AMD-64 box with no frills.
QUESTION:
It seems that Tables have to be separately and explicitly declared in
the nftables script/ruleset.
But is it essential to declare tables which will not needed for example MANGLE and RAW?
And how will will the traffic filtering be affected if these tables are ommitted (i.e. deliberately not declared) ?
Can anyone help please?
Thanks in advance.
