Installed 'nftables'. According to the documentation (https://wiki.debian.org/nftables) there are no filter rules by
default,so the assumption is that there is no filtration of packets by the software at the kernel stage. 

The configuration file '/etc/nftables.conf':

#!/usr/sbin/nft -f

flush ruleset

table inet filter {
        chain input {
                type filter hook input priority 0;
        }
        chain forward {
                type filter hook forward priority 0;
        }
        chain output {
                type filter hook output priority 0;
        }
}

Is it correct to interpret this configuration file that filtration is _not_ active?
