Hi list,
I'm studying nftables. I'm using CentOS 8.1 (Gnome) and I disabled
firewalld. I noticed that a default policy is created with tables and
chains probably for firewalld.
So I created a .nft script where I stored my rules with a flush for
previous ruleset, then saved on /etc/sysconfig/nftables.conf and the
enabled nftables service.
Running the script with nft -f script.nft all work as expected but when
rebooting, running nft list ruleset I find my rules and the default
policy (chains and tables) that I would not have in my configuration.
My nftables.conf contains only my ruleset.
For example, running nft list tables I found several default tables like:
table ip filter
table ip6 filter
table bridge filter
table ip nat
table ip mangle
So probably there is something that is applying its policy but I ignore
what is.
Can someone point me in the right direction?
Thank you in advance.
